Why do some people clap at movies?
I mean, I can understand that people clap at plays and concerts. After all, the actors and musicians are there, and they can see you and hear you and they are the sorts with the psychologies that thrive on recognition. In a cinema, however, the producer is not there, nor is the director, nor the actors, nor the composer of the musical score, nor the camera gaffmen, nor anyone who had anything remotely to do with the production of the film. Still, in many cinemas, people insist on applauding and hooting and hollering at the end. Why do they do that?
