I (40sM) am a musician. Not like a "annoying guy with guitar at parties" or some dude who does open mic nights. I"m a studio musician whose worked on soundtracks, like for Marvel or Harry Potter.
My SIL (30sF) is getting married in a few months. My wife is her bridesmaid and our daughter (6F) is a flower girl. Originally, my son (12M) and I were going to stick with each other. But my SIL asked, or more like voluntold me, that she wanted me to play music during the interlude before the wedding and during cocktail hour.
Apparently, she'd been telling her friends and in-laws about my work and would love it if I played for them.
I told her I can't because I don't want to work during my off day. I'd be playing for hours, and it can get tiring. Also, I'd be leaving my son alone in that time. He isn't in the wedding party and doesn't have anything to do. He's also been struggling with his mental health and I don't feel comfortable leaving him alone.
Well, she didn't take it well because now she's telling these same people I'm being an lazy ass just because I won't play during her cocktail hour. My in-laws, her parents, are asking me to reconsider because this would mean a lot to her and it would be easy for her if I just do it as a favor.
My wife is sticking up for me, at least, but my SIL has been kind of a dick to me since. I may consider skipping the whole thing and just take my son out for the day.
AITA?
