Why?

Why are people like that?
Why does everyone in the train look so upset?
Why doesn't anyone commute smiling?
Why do people, in general, don't give a damn about each other?
Why are there people whose goal in life is to harm other people?
Why do so many believe in wrong, superfluous, stupid things?
Why don't they make barbecues?
Why don't they open a beer?
Why don't they embrace a friend?
Why the bombs?
Why revenge?
Why selfishness?
Why jealousy?
Why so many small, greedy things?
Why? Why? Why???
