This evening, FI and I have to attend his niece's first birthday party. It's an hour or so away, and his mother just called him, crying because she can't afford gas money to get to the party.
He agreed she could ride with us. Considering I would rather have a colonoscopy than spend two hours locked in a car with her, I am not looking forward to this evening.
Here's my problem: she will repeatedly ask tons of wedding questions. FI and I agreed we don't want her to know all the details. We want her to have no more involvement than the average guest. She knows when and where, and that's about it.
I am well aware of the bean-dip technique, but I don't think it will work in this situation. After two hours of me trying to change the subject, she will undoubtedly know I do not want to discuss the wedding, yet she will not back off. She has some issues, to put it mildly. I can guarantee she will also talk trash about me at the party and after if I don't tell her all the details.
How can I make this evening less awkward? I don't want to upset his mother (even though I'd be thrilled if we could move and not tell her), but I don't want to tell her all the details, either. Suggestions?
