He just outed his sister's pregnancy on Facebook. He commented on a post, which led to a couple more posts, prompting her to email the family and tell everyone. She's about 14 weeks now, and told him she was fine with it because she was trying to figure out how to announce it.
I told him I'd be fucking livid if someone did that to me and that he needs to think about shit before doing it. I think he feels bad about it. When I said something, he had that moment of realization. Like, oh fuck. Dumbass.
