Choosing not to post the receipts is sometimes stronger than posting them. You keep the power and the peace.

Having proof creates a strong pull to use it, because the case is right there and winning would take thirty seconds. What posting actually does is spend the proof and start a second fight, this one in public and with an audience that will keep it alive long after you are bored of it. Holding it keeps both the quiet and the option.

If you are sitting on screenshots, wait a week before doing anything with them. Show one person you trust if you need a witness. Most of the time the week is enough and the whole thing passes.
