DEAR ABBY: My brother-in-law, a doctor, had an affair a few years ago with his nurse. It destroyed his more than 20-year marriage to my former sister-in-law. He married the nurse.
I want nothing to do with him or his new wife now. He stayed with us for a while and lied about the affair. I have no respect for either of them. I usually ignore them at family gatherings because I don't like to associate with people who do not share my values. Abby, do you think I should accept his new wife? -- PRINCIPLED IN DAYTON
DEAR PRINCIPLED: Good manners dictate that when you see them you be civil to them. It doesn't have to extend beyond, "Hello. How are you?" and moving on to talk with other relatives -- and it doesn't indicate "acceptance."
