Q: [part 3] But now I only see him at school because he moved house, which means we really don't talk anymore. I don't want to ask him about this thing because maybe he doesn't even know that he acts like this, idk. to make things clear: he has the same behaviour towards my friend who grow up with him as well. He used to talk to her a little bit when our parents met but one time when she was at my school because of a party, she said hi when he walked by but he ignored her... that's confusing...
