When cartoonist Charles Schulz dined in the home of a friend, the host remarked that he needed to set off his dinner jacket. He disappeared and returned a few minutes with a heavy chain from which a medallion hung, and across the face of the medallion were the letters “love.”

Schultz fingered it for a few minutes and then handed it back. With a wry “Charley Brown” smile on his face, he said, “It’s just too hard for me. Do you have one that says, LIKE?”
