To start with, a few simple facts: Watching a movie in a cinema is not contagious.
Going to a concert doesn't make you sick.
You don't get Covid-19 from looking at pictures in the museum.
Reading books in a library does not cause coronavirus infection.
What is dangerous is inhaling aerosols that an infected person has just exhaled. But you don't have to do that when you are in the cinema or theater, in the shoe store, in the museum, in the café, in the library or in the office. Even at school you don't necessarily have to inhale aerosols that someone else has just exhaled.
