Before you start
Set a trap
Build five questions about yourself. For each one you pick the true answer, then three decoys to hide it in.
a stranger
knows you well
Each question is rated by two imagined guessers. You are trying to make that gap as wide as you can.
Nobody is going to take this. There is no link and nothing is kept. What you get back is a reading of the trap itself: whether someone close to you would pass it, and whether a stranger would fail.
