If a person is not famous, why do people watch that person(they don't do anything illegal). What makes people superstitious?

Answer 1

Perhaps the person behaves in a way that is not usual in that particular society.
Perhaps the person has a dynamic personality; perhaps the person is very attractive. There are many reason that a person who is not famous may draw interest.

Here are a couple of interesting sites on superstitions:
