Samuel Beckett is an famous Irish writer best known for creating radical new dramatic form.
He somehow does not like realism,his works usually don't have connected plots. His style is expressing human's pain.

There are four characters in a dark room
Blind cannot stand
Servant cannot sit
Blind's father has no legs
Blind's mom has no legs
They talks without topics

His works are pretty much sad story.
He thought humors always based on pain.
