Do you ever just sit and People watch?  I find it interesting and engaging.  In case you dont know people watching is observing people and their everyday interactions, usually without them knowing you are observing them.
yes
Some people participate in in people watching as hobby.  I don't think I would take it that far, but I do enjoy it from time to time.
sure
Other people dont even realize they are people watching they just do it without thinking about it.    DO You ever find yourself doing that?
yes
Me too!!   If you are going to people watch your should follow the Expectation of Privacy Principles  and not be unethical or put down the people you are watching
