So I'm M\[16\] and my little brother is M\[12\]. We've been watching a certain show together for a long time (I'm not going to say the name to avoid spoilers). However a couple months ago my brother got a spoiler for the ending of the show and ever since then, everytime I do something he doesn't like he says that he'll spoil the ending for me. A few nights ago I did something that made our mom mad and she punished the both of us. The punishment didn't rly affect me cuz I've been through this before and I know how my mom is, but my brother was crying. Now here's where I mess up because I began laughing. I guess I pushed my luck cuz he then spoiled the show for me.. I know this isnt the biggest deal in the world but that show is genuienly one of the few peices of media I acually got properly invested in. No other movie or anything I've seen has pulled me in like that. And now its all ruined cuz my brother was mad over a temporary punishment. AITA for laughing at him after he was crying cuz of a punishment I caused?
