I expect I don't benefit from knowing who people really are. If they have any power over me it matters. Otherwise who cares what they are?

If you are financially involved with anyone then of course it matters if the person is a skunk a liar a cheater a betrayer. Otherwise? Naw.  So you feel ridikkalus if you find out the person you thought you knew you don't. So what? Life is full of situations that can make you feel ridikkalus. You survive them and move on.

So liar or not. Cheater or not. Betrayer or not. Skunk or not. Where is the exposure/danger?
