Instead of loving your enemies - treat your friends a little... - E. W. Howe

"The little trouble in the world that is not due to love is due to friendship."

"When a friend is in trouble, don't annoy him by asking if there is anything you can do. Think up something appropriate and do it."

"It may be a cold, clammy thing to say, but those that treat friendship the same as any other selfishness seem to get the most out of it."
