My fiancé has made it VERY clear that none of our parents will ever live with us, which is disheartening to someone whose folks are getting on in age and live across the country
Yeah I really didn't think twice before I agreed to it, 63 year old lady and my apartment had a spare room. It's family, why not? But over the course of 20 months I probably had two encounters that weren't terrible, and I think they both involved gift giving.
Can't say it's always destined to fail, but holy shit. I'd recommend starting a good relationship with them beforehand, ground rules, a trial period, and some contingency plans
Oh and here's a weird kicker now that I mention a trial period: we let her cousin stay during his travels for a little bit. Come to find out later that the guy is a roaming child molester. Luckily he really didn't spend time away from us around the neighborhood or anything.
