I'm struggling with this for some reason. Sorry if this is too self centered, but this discussion has exposed some holes in my concept of trust.
Reading all the responses has me thinking that what I have been thinking was trust, is for me just a set of assumptions about how people will behave. What else do I have to trust others with? Secrets? I have shared pretty much everything that's happened to me with someone, sometime. If they turned around and told someone else, I don't really care. That they will be there to catch me if I fall? I've fallen and landed pretty hard, got up and moved on.
I will readily admit to being a bit of a flake, so I tend to not put myself in situations where someone has to trust me beyond basic human decency and politeness, like maybe what is laid out in the ten commandments, or traffic rules. (I know, everyone drives like maniacs, but really, traffic is pretty predictable) Those are things that I assume I can trust others with, as well. Beyond that, I don't place much trust in others, and would rather others not trust me as well. Too much of a burden.
I think I am too forgiving to not trust others, but I have never been really hurt by another, not in a permanent, scarring way at least. Good fortune or good judgement? Low expectations or too forgiving? I've spent a great deal of time by myself, I work independently for the most part, have few friends, none of which I would call close, I am in a long term relationship, but is it going to last? Really, what am I trusting others with?
