My best friend got married last weekend. I was super excited for her, helped with a lot of planning, and even paid extra to get a dress that matched her aesthetic. When I arrived at the reception, I went to find my table and realized I'm not seated with the rest of our friend group. I tried finding my place and it was at the kids table, surrounded by her little cousins, who were all between 6 to12 years old. I thought it was a mistake. But when I asked about it, she laughed and said, It’s just a joke. You’re basically a big kid anyway, you’ll survive. Everyone else at the adult table and even our friends laugh at me, and enjoying normal conversations, while I was trying to keep a 7 year old from spilling soda on my dress. Other guests kept coming up and asking why I was sitting there, and I had to awkwardly explain. Even photographer made a comment. I stayed through dinner, at the same time I felt so uncomfortable and honestly disrespected that I left before the cake and dancing. After a day we met and she told me that i'm rude for leaving early and that I should’ve been able to take a joke. Did I made her look bad by disappearing. I don't want to cause drama, but I really don’t think I was wrong for leaving after being publicly embarrassed. So AITA for leaving my best friend’s wedding early?
