Trust is a funny thing, you can be so close to somebody and yet they will spill the beans in seconds, and you can have somebody who your not so close to, but have them as somebody to talk to who you can trust. I get told things to be kept secret by a few who I wouldnt say I was that close to, so I would like to think im trustworthy
On the other hand, I tend to keep my feelings/thoughts and whatnot in my own head, although people pick up because I go quiet aha. Id say I could trust a good 4/5 people.
