27-year-old bails on sister's wedding after he's seated at 'kids' table,' 'I was HUMILIATED.' AITA?

"AITA for leaving my sister's wedding early because she put me at the 'kids table?'"

So I (27M) recently attended my older sister’s (30F) wedding. She and I have a good relationship — not super close, but we’ve never had any serious issues. I was genuinely excited for her big day and happy to be there to support her.

But here's the thing: at the reception, I found out I was seated at a table with literal children. Like, we’re talking 10-year-olds, teens, and one baby in a high chair. I double-checked the seating chart thinking maybe it was a mistake, but nope — that was my assigned seat.

Meanwhile, my cousins (same age as me) and their partners got seated with the rest of the adults. I don’t have a partner right now, and I guess because I’m single and “the funny uncle” type, my sister thought it’d be cute or something?

I tried to laugh it off at first, but after about 45 minutes of listening to one kid talk about Minecraft and another one throw a bread roll at me, I just…left. Quietly. No scene. I texted my sister congrats and told her I wasn’t feeling well.

She found out later that I left because of the seating and blew up my phone with texts saying I was being dramatic and selfish and that I “ruined the vibe.” My mom also said it was childish to leave over “a joke.”

But was it a joke? I felt humiliated. And honestly, I didn’t want to be that guy making a scene during the wedding, so I thought leaving was the more respectful option. AITA for walking out?

Here's what people had to say about this one:

NTA. You left quietly without drama. Your mom covering for your sister saying it was a joke? Who decides to prank someone at their sibling's wedding. Obviously your mom knew about this ahead of time and didn't say anything.

NTA. I would have grabbed my gift back, too.

NTA. Younger kids should have been seated with their parents if your sister didn't provide child care. If I were you, I would have just moved my seat and place setting to sit with other family or friends.

NTA - Jokes are meant to be funny this was not. It might have been funny if she did it for a minute and then gave you a regular seat (Depending on the relationship you two have the sense of humor that is in it) but what she did was completely disrespectful.

NTA, how is that a "joke," how would your mother have liked it if SHE had been sat at the kids table? Would she think it was a "joke" then? How did you "ruin" the vibe? The clearly didn't even know you had left.

NTA. You don't joke with people like that on your wedding. Now invite your sister & BIL, parents and trusted friends for dinner, serve your sister baby food while every one else get steak and talk about what happened at the wedding.

NTA. That wasn’t a joke, it was disrespectful. You left quietly and avoided drama. Honestly, she owes you an apology.
