"Did you ever have a bad day? Everything seems to go wrong and you are completely lost in anger, frustration, and self-pity. It gets worse and worse, until the final moment when, say, you have just missed the last bus. There is some critical point where it gets so bad the absurdity of it all overwhelms you and you can do nothing but laugh. At that moment you up level your predicament, you see the cosmic joke in your own suffering."
