Dear Prudence,
My wife and my mother get along fine, though they’re not very close and have little in common (besides me). My mother is a talker; there’s nothing objectionable in the content, but she can yammer on for hours about trivial nonsense, which is something I’ve learned to accept. My wife is pregnant with our second child and hormonal. Next month, we are all carpooling to a wedding about four hours away. My wife has told me she plans to wear headphones for the entire drive because, in her sensitive state, my mom would drive her nuts. I sympathize with my wife, but I think the plan is terribly rude and that she just needs to suck it up. She’s given me an ultimatum: If I object to the headphones, she won’t come to the wedding. Who’s right?
