That's not how it works. My privacy perception has nothing to do with another person's trust in me. And no I did not say I am volunteering ALL the information I am privy to - I did say that I have my boundaries. How I define those boundaries will obviously take into consideration what I think is a mutually understood contract between me and another person. But those boundaries vary from person to person and so it is futile to try to define someone else's privacy perception objectively.
