This weekend visiting family I recalled a piece of advice I heard early in recovery:
“Don’t do anything you’ll have to make amends for later.” That is a kind of a failsafe slogan. I remember that it had a lot of impact after I had been working the 9th step and remembered how grisly some amends can be. This slogan reminds me that it can be very selfish and very self-protective to NOT get the last word and NOT make my point.
If you can’t do anything else: Just don’t do anything you're gonna have to make amends for later.
