Hmmmm .... would you?

There's this guy I talk to on msn a lot but I've only met him once which was a while ago, mostly for y times haha well anyway when I was with him he called me gorgeous and all that, which is pre normal. Just before though he told me he's going out with his mates on the weekend and he wants me to come, which is kind of weird because i don't really know him and I didn't even know we were on friendly terms. I guess I like him, though, so I don't want to let him down. But like, yeah. I guess my question is, should I like be scared? Could it be like a set up or something. It doesnt seem like it, but i'm the kind of person who never sees the danger in anything. I don't even know why he asked me =s
