Friendship is born at that moment when one person says to another: “What! You, too? Thought I was the only one.

C. S. Lewis

Friendship is unnecessary, like philosophy, like art… It has no survival value; rather is one of those things that give value to survival.

C. S. Lewis (1898 – 1963), An Irish academic, medievalist, literary critic, essayist, and Christian apologist.
