Karen (the wedding planner) asked the happy couple if there was anything she should worry about as she made preparations for their wedding. They assured her there was nothing. They lied.
It Should Have Been An Easy, Nice Wedding

Karen is a part-time event planner. It’s a side hustle for her because she usually enjoys it and can make decent money. She doesn’t ever want to do it full time because, as she explains, “there would be diminishing returns by doing so (more pay but way more stress). So I do a couple a year and that’s usually enough to satisfy my itch and gives me some good crazy people stories.” This is one of those “good crazy people stories.”
Karen only took the gig because it “was for a friend from high school and I knew his bride from school as well. He was struggling to find someone in their budget who wasn’t also juggling 10 different weddings at once. They’re nice people. He’s a war vet and they have one of the cutest sons I’ve ever seen, so I said yes and discounted my rate as their wedding gift.”
Karen asked the happy couple if there was anything she should worry about as she made preparations for their wedding. They assured her there was nothing. They lied.
The Rehearsal Begins Without The Mother Of The Groom

Karen and the wedding party have about an hour set aside for the wedding rehearsal, on the night before the wedding. At this point, she had never actually met the groom’s mother, Agnes, and hadn’t even heard much about her. The groom’s stepmother had been more involved in the planning at this point.
Agnes was supposed to be at the rehearsal. She wasn’t. At least, she wasn’t at first. Eventually, she arrived and made her entrance in a grandiose fashion.
“I was a bit blindsided when, 56 minutes into the hour-long rehearsal, [Agnes] came running in. I mean, full sprint running, and this lady had never run a day in her life. She threw the doors open in the loudest fashion and announce to us through gasps of air: ‘I (heavy breathing) have ma-(wheeze, wheeze) made it. Whew…I’m feeling a little light headed. Where can I sit down?’ All this while fanning herself and swaying dramatically while one of the groomsmen apathetically found her a chair.”
Karen might have been shocked at the way Agnes appeared, but she quickly regained her composure. Then, as you might expect, the mother got very bossy. “After she had gotten a chair delivered to the middle of the doorway, was given water, and after 10 full minutes ticked by, she snapped her fingers at me.
Agnes: ‘Girl—yeah, wedding girl! When do I walk down?’
Karen: ‘Well, I’m sorry you missed your portion of rehearsal, you’ll be—‘
Agnes: ‘Oh. Well, since I’m here let’s just run it again!'”
Oh no, she’s going to be one of those. “I hate being late and equally loathe running over time, so she’s officially on my naughty list.” Not only was Agnes entirely too late to run through any part of the rehearsal, her sudden appearance had also thrown a monkey wrench into dinner plans. The reservation for the restaurant was in ten minutes, but it’d take 15 minutes to get there.
You could hear in Karen’s words that she was unhappy with the situation, but she held her ground, telling the mother, “WELL, as I was saying before, I’m sorry you missed your portion of rehearsal but we can discuss your walking role over dinner. Rehearsal has been officially over for a few minutes now.”
With that, Agnes exploded, “Well excuse me! My blood sugar was low and I needed to eat!” Mind you, this meant she stopped for something to eat…on her way to the rehearsal DINNER.
Karen didn’t find this amusing, writing sarcastically, “I sympathize. Waiting an hour in between full meals is certainly trying. Especially when we had some light snacks available, of which everyone had been informed.”
This was truly only the beginning of the mess that this crazy mother would make.
Mother Dearest Made The Dinner All About Her

As the wedding party was walking out of the venue on their way to the restaurant, Karen noticed Agnes and her ex-husband, the father of the groom, exchanging some nasty words. But she, and everyone else, decided it would be best to just ignore and pretend it never happened.
Karen had made the reservations at the restaurant, so she called ahead to let them know the wedding party was on the way, though they would be late, thanks to a certain somebody.
They all arrived in due time, except for, you guessed it, Agnes. Obviously, her penchant for dramatic entrances was something of a constant. Karen described the scene when the groom’s mother finally arrived: “She loftily strolled in right after we have all placed our orders and all the bread had been eaten. Unfortunately for me, I sat at the very end to stay out of everyone’s way and now the only place to sit [Agnes] was next to me. Everyone was avoiding her eye contact so I got to break the bad news that we had already ordered.” Uh oh.
That is when she just lost it.
A mortified Karen explained, “[Agnes] made an incredible fuss, wailed a little through some fake tears that she was getting edged out by the groom’s stepmom and how dare she try to take her place. This was all mixed in with her pleading with her son to ‘take pity on the woman who had to get 10 stitches after birthing his big old head.'”
At this point, Karen’s jaw had dropped so often over the course of the night that she worried that it’d be permanently stuck that way. Agnes still had more crazy to share with everyone, though.
Some Early Signs Of Ugliness

Karen decided this was the moment to take the crying mother of the groom out the restaurant before she made more of a scene. She’d already gone into more depth about the groom’s birth than anyone wanted and martyred herself at the feet of the groom’s stepmother. It was time to go.
Karen got Agnes outside, calmed her down a little bit, and eventually convinced her to go home and sleep it off. Apparently, the mother realized she’d gone too far, and asked Karen “not to tell her son about her outburst (he was there, watching it) and that she’s a very good person.”
Karen went back inside, fully expecting the bride and groom to ask her to make sure the groom’s mother doesn’t return the next day for more drama, but to her surprise, that wasn’t the case. “I was floored when they BOTH told me they weren’t planning on uninviting her. The bride said, ‘Weddings bring out the worst in people and I mean, it IS the night before, so I understand her not handling everything perfectly.’
The groom replied, ‘I mean she does have a point. We have been including my dad and stepmom in the plans pretty heavily and I don’t blame her for feeling excluded.'”
Karen was floored, but she moved on. The big day was quickly approaching. When she asked the bride and groom if they were absolutely sure they wanted Agnes to be at the wedding, they uttered the cursed phrase, “What could possibly go wrong?” If only they knew…
The Last To Arrive And Wearing Athleasure Wear, Not Formal Wear

The next morning, Karen arrived at the venue early and began setting up. There were a lot of decorations to put together still and, since the wedding was on a tight budget, it was up to her to make everything look spectacular. She pulled it off, though, with some help from the wonderful members of the wedding party who all chipped in to help get everything ready for the bride and groom’s big moment. “We spent three hours building and putting up our creations, making it one of the best transformations of a space I have ever accomplished,” Karen was proud to say.
Then came time for the wedding. And who was so late Karen was beginning to hope she wouldn’t show up? You guessed it, the groom’s mother. Karen was shocked to see Agnes stroll in, “15 minutes before the wedding. To Karen’s even bigger surprise, both Agnes and her new husband were “rocking sweats and eating fast food.”
That’s right, the wedding was only moments from starting and the mother of the groom was only now arriving, stuffing a chicken sandwich in her face and wearing sweatpants, not at all in the dress she was supposed to be wearing.
Houston, we have (another) problem.
More Insane Demands

Karen was nearly speechless with both anger and shock. “I sputtered a little when I saw her and took her off to the side before groom or bride saw her because they did not need this drama today.”
She confronted the woman, demanding, “Why on earth are you not dressed?”
The mother replied, spitting half-chewed bits of her sandwich at Karen through her words, “Well, isn’t it the bridesmaids’ jobs to dress me?”
“Apparently,” Karen mused, “she has only attended her own weddings so she doesn’t understand that no, this is not the actual case.”
Agnes couldn’t believe that she didn’t get her own special crew to literally dress her minutes before her son’s wedding. As Karen wrote, “Indignation ensued” after she was denied the services of the bridesmaids. When she learned the bad news, she exploded, “But where on earth am I to get dressed? The bathroom?”
Yep! That’s exactly what Karen ended up telling her to do. “Actually,” she said, her face serious, but her eyes full of mischief, “That’s a great call. I’m glad you were able to problem solve this for yourself.”
And Karen led her away, towards the ladies’ room, where she thought Agnes would do the least harm. Little did she know, the harm had already been done.
Poor Karen Had Her Hands Full Trying To Contain Agnes’ Chaos

When Agnes emerged from the bathroom, she was wearing a grey dress. It was supposed to be light blue, but honestly, that was the least of Karen’s worries. She rolled her eyes and moved Agnes into position. It was then that Karen realized that there were only a handful of guests. She figured that there might have been some traffic delays, but nothing that should have kept most of the 150 RSVP’d guests from being on time. At the moment, there were only about ten people.
A few more people trickled in, but the wedding had been delayed long enough and the venue wanted the show to go on. Karen consulted with the groom’s father, who decided to make some calls and see where people are.
What the groom’s father found out was completely insane. It turns out his ex, Agnes, had called “almost the entire guest list, announcing that at dinner the night before, it came out that groom was not his son’s father and the wedding had been called off. And because there was a lot of vague chatter about drama from the rehearsal dinner, a lot of guests believed them. A few knew that she was full of crap and came anyway, and the rest were people she couldn’t reach in time.”
That’s right, she canceled the wedding, as best she could. This was the work of a complete psychopath. And it wasn’t all she did.
The Sabotage Continues

The ceremony was finally held, despite the only 35 people out of 150 in attendance. With a doubt, everyone must have been holding their breath when they got to the part where the priests asked if anyone knows a reason the couple shouldn’t be married. Luckily, the crazy mother of the groom stayed quiet.
When the ceremony was over, the party left the room while Karen changed it over for dinner. It was while she was setting up the tables and the chairs that the next bomb dropped. Karen asked the caterers about the plated, sit-down dinner. That’s when they informed her, “That’s not what our invoice is for.”
She was stunned. She’d had issues with this company in the past and she suspected that they had messed up, AGAIN. So she asked to see the invoice and sure enough, the order had been “changed three days prior to just a couple of appetizers. And when I say a couple, I mean there were two options and both of them were tiny skewers. Everyone who arrived had been told there would be a plated dinner and expected as such.”
Karen didn’t even have to guess who could have possibly done this. Yep, Agnes strikes again! And then she consumed way too many drinks making the nightmare even worse for everyone.
A Culmination In Blood

That’s right, the mother of the groom hadn’t done enough to ruin her son’s big day, so she guzzled some drinks and, during the bride’s dance with her father, stumbled onto the middle of the dance floor. Then she…well, here’s how Karen describes it:
“She continued the previous night’s tirade and started stripping her clothes off until she was in her slip. Then she went off about how her son was the man she was closest to who had been in the deepest. She paused for a second before she said, ‘Deepest in my heart.’ She also said she thinks the bride is a big old see you next Tuesday and that she hopes grandson isn’t really her grandson because she doesn’t want the bride to muddy his genes!
She ran around during this rant, which kept anyone from stopping her until she threw a glass at her ex and popped off about how her life has been so horrible since he left her 12 years ago. Some glass ended up hitting bride’s father, who happened to be dying from cancer, so his cheek caved in and he was bleeding like a nightmare.”
The night ended with the cops being called and one guest bloodied. The bride and groom cut off all ties with Agnes, which was a given considering everything she’d done. Watching a mother purposefully sabotage her own son’s wedding definitely left a sour touch in Karen’s mouth. Safe to say, she will probably stop moonlighting as a wedding planner.
