Sir 19:7-12 Never repeat a conversation, and you will lose nothing at all. With friend or foe do not report it, and unless it would be a sin for you, do not disclose it; for some one has heard you and watched you, and when the time comes he will hate you. Have you heard a word? Let it die with you. Be brave! It will not make you burst! With such a word a fool will suffer pangs like a woman in labor with a child. Like an arrow stuck in the flesh of the thigh, so is a word inside a fool.
I love that. Won't make you burst! This is one of those post it notes, but my mind never seems to find it fast enough before I talk.
