The law does not pretend to punish everything that is dishonest. That would seriously interfere with business.
Sometimes I eavesdrop on people. I could rationalize it - oh, this is good anthropological research for characters I'm writing - but it's basically just nosiness. It also helps me gauge where I'm at: Am I normal?
We're not children here. The law is-how should I put it? A convenience. Or a convenience for some people, and an inconvenience for other people.
