I trust people with information about my life because they cannot hurt me with truths I know and share, and I trust most people not to be violent maniacs so I don’t have to be in fight or flight all the time I’m around them (and you can usually tell when they are). As such, I’m a very friendly guy who talks to and listens to everyone. I don’t really need people one way or another though (yes, it comes from a somewhat difficult and lonely childhood but at least it’s made me independent), so I don’t mind letting them get close and I don’t have any expectations of them besides the basic ones. I trust people to be people, not to be mentors or even helpful (and I always appreciate it if they are!).
