“You are interested in a person, not in life, and people die or leave us ... But if you are interested in life it never lets you down. I am interested in the blueness of cheese. You don't do crosswords, do you, Mr. Wormold? I do, and they are like people: one reaches an end. I can finish any crossword within an hour, but I have a discovery concerning the blueness of cheese that will never come to a conclusion.”
