DEAR ABBY: For years, my sister has been planning to retire and move in with my husband and me. She lives out of state, so this is a major move for her. It was never a problem — until now. She is a strong anti-vax advocate and refuses to get vaccinated for COVID. My husband said she can’t move in with us unless she is. How can I tell her diplomatically that she’s no longer welcome to live with us? This is really upsetting for me, and I would appreciate your advice. — DISTRAUGHT IN MICHIGAN

DEAR DISTRAUGHT: Whether to get vaccinated is a personal choice. You have made yours, and she has made hers. Quit being “diplomatic,” and don’t debate this with her. TELL her the terms under which she is welcome to move in. If she cannot meet those terms, she will have to make other living arrangements. PERIOD.
