[A bore is] a guy who wraps up a two-minute idea in a two-hour vocabulary. - Walter Winchell

People always get tired of one another. I grow tired of myself whenever I am left alone for ten minutes, and I am certain that I am fonder of myself than anyone can be of another person. - Bertrand Russell
