I trust cats, mostly. People? I trust them in areas I feel
  they're trustworthy in, but in other areas, I keep guarded. I
  trust, for example, that you're likely to post thoughts that are
  in earnest. Someone else, I might trust that what they post is
  meant sarcastically, etc. So, I have layers of trust with people
  [this woman/man will probably not rape me right now but I won't
  sign a contract for a business partnership just now].
