How do you know? Have you told them EVERYTHING?
I have a friend I have yet to stun with my stories, thoughts, theories or actions.
I know I can tell her everything and even if she raises an eyebrow, she will either accept the information as part of who I am and deal accordingly, admit that she's done, felt or thought the same things or she will at least listen when I try to rationalize the situation by explaining the 'how' or 'why'
I really, really appreciate that friend.
