Help! Advice, comments appreciated? Plz read on...This guy I know, I asked him around with a couple of others?

(purely as friends), I didn't know him that well but he seemed pretty normal so when he came over with my other friend it turned out my brother and his mate were there too. We wanted this guy to leave because he started to say really stupid and uncomfortable things so we asked him to leave. He wouldnt go but eventually we got him out of the door but he just tried to pick the lock and get back in. I told him to go and find some friends that like him and he kept trying to get in by attempting to pick the lock. He went around to the side door and got in and asked questions about giving him a second chance.





He started to cry and he eventually left and hen my brother went off at me for inviting him over. I thought he was reasonably normal but it turns out he has aspergers and bipolar. I feel really bad and im scared that people like my brothers friends are going to be mean to me about it and stuff. I feel like an idiot. What should I do?Help! Advice, comments appreciated?

Don't feel bad, it happens. Do make sure what kind of people you bring into your circle. especially when your brother is involved. As for what other people say you cant help it. Just know the people you show your home to.
