I let people think I'm naive. It works very well. They think
  you're an idiot and say things around you. I let them believe
  it. Make fun of me in front of me and believing I don't know it?
  Go ahead. I'm listening. Plotting. Planning. ... lol no,
  actually I just feel pity. People who think they're above me
  (usually because I'm a man and it's a small group of women
  talking amongst themselves about me) can have their smug
  "above-me"-ness. I know what's what. I also know not to let them
  know that I know. tongue emoticon People are sometimes less
  stupid than they at first appear. == One of Ken's Rules: When
  someone says or believes, "I'm good at reading people". or "I
  can tell what a person is like within a few seconds", I know
  they're awful at it. I watch and observe. They're awful at it.
  Easily taken by sweet talkers. Yet they continue to believe
  their first impressions are correct. But first impressions are
  usually wrong. Even if they're right, you can't stop at a first
  impression because you could be wrong.
