My dad once wrote me a card, when I was about 16 or 17, that came with a word processor as a gift. The card said:
“Words, words, all so real
Bad words anger, good words heal.”
It’s probably a quote, though he could have made it up. In any case, it stuck with me much longer than the word processor did.
