We are not the same persons this year as last ; nor are those we love. It is a happy chance if we, changing, continue to love a changed person. - William Somerset Maugham

The isn't only a sunny place for shady people.

"You know, a thing that has always struck me is people's fiendish eagerness to give anyone away. They pretend it's public spirit, I don't believe a word of it; I don't believe it's even, as a rule anyway, the desire for notoriety; I believe it's just due to the baseness of human nature that gets a kick out of injuring others. There's a whole mass of people who can't wait if they have the chance of doing down someone who's trying to get away with anything."

Said in 1921. Quoted in The Guinness Dictionary of Sports Quotations (1990), p. 75
