My sister 23 F is creating a team to participate in a walk (an annual event) the day after my wedding(26 F). This cause is near and dear for her and my whole family is participating in it. Unfortunately i can not participate in it because my fiance and I have PAID a lot of money to host a brunch that has been in the works for over a year.

My immediate family is ditching my brunch to attend the walk and now she is trying to get my extended family. It feels like a competition and it is making me upset because we have spent so much time planning our wedding weekend. My mom told me that they are all going on the walk that is an annual event in our town.

AITA for being upset over the walk that is taking place during my brunch and AITA because I am not attending the walk?

I am going out with a few friends this weekend. My sister called me to see what I was doing. I was hesitant to tell her because I didn’t invite her. It’s not because I don’t want her to go, but because I wanted a more intimate setting. She then asked me if I could join and I said I don’t know because I didn’t want to hurt her feelings. I ended up saying no because I found it rude of her to invite herself. Am I the asshole for telling her no? I feel really guilty, but these plans were made a week ago and she wasn’t included.
