Better the Furnace Than Shaming Another
A person's honor is so precious that Rashbi would rather see one burn than see another publicly put to shame.
In Rebbi Shimon bar Yochai's name, the Gemara teaches that a person should rather let himself be thrown into a fiery furnace than shame another person in public. The proof comes from Tamar. She was being brought out to be burned, yet she did not announce that Yehuda was the father of her child. She sent his signet, cord and staff and left it to him to recognize them, preferring her own death to publicly embarrassing him. Yehuda saw what she had done and said that she was more righteous than he. Rashbi, who knew exile and the threat of execution, ranked a human being's dignity above his own safety. When it comes to words spoken in front of others, we should treat them as if a life depends on them.

If you must correct, disagree with or remind someone today, do it privately and gently, never in front of others. Before you speak at a table or in a group, take one breath and ask whether your words could make someone blush. If one could, rephrase it or wait until you are alone with that person. Should you have embarrassed someone recently, reach out this week and apologize sincerely. Rashbi counted dignity as something worth guarding at great cost, and you can guard it with very small choices.
