Kurhea: I agree don't talk to him if the police will be called. Even if the police aren't as forceful as in the US, you've already had dealings with them being called before. You don't want to end up in jail for a misunderstanding.

Just be careful.
Punky:

being a parent is hard. Maybe they are not jealous exactly but maybe they don't understand what she is going through. I think it might be hard to say "I had the same mom and dad and I'm fine, so why is something wrong with her?" Plus, it's invisible. My oldest son's cousin has pretty sever autism, but he just looks like a noraml kid, you know? So, when he starts throwing a tantrum all people see is a 12 year old boy acting like a brat rather than a kid with autism becoming overwhelmed.
