Ummmm, I don't think anyone can answer that but you. I can trust a few of my neighbors. Not all. You need to decide that for yourself. Also, if I call someone a friend, I can trust them. If I can't trust them I call them aquaintances/someone I know.
I have a rule: If you haven't sit on my couch and propped your feet up, you're not a friend. Just someone I know. I trust VERY few people outside of SOME family. The ones I do trust have proven they are worthy of that trust.
