I trust me. I trust me to take care of me and make decisions that are in my best interest. However, there are other people I do not trust with me, and it has nothing to do with me trusting myself.
It has everything to do with them being untrustworthy people. I can always pick myself up and dust myself off no matter what anyone else does to me, no matter how heinous, doesn't mean I will trust the offender again. At some point that would simply make me a fool.
