That's got to be a tough one being it's the wife....
I have enough disaster stories to fill a book, but I'll just add one that was inflicted by a family member.
I was in my early 20's and still living at the folks. (Yeah, I know!) One day, while at work, my dad decided he would paint the ceiling in my room. No advance notice, no chance to prepare.
He was always the type who believed in getting these projects done in as little time as possible and waste no time with things like masking, paint tarps, drop cloths, etc. He would paint over anything like hinges, light switches, outlets, etc.
I came home to find that not only were some things broken, but the worst was everything in my room was covered with paint splatters, and those little droplets of paint that go everywhere when using a roller! This included my furniture, stereo equipment, and my small model collection! I ended up tossing some of them out. Latex paint does not easily come off when dry!
Somehow, I was the bad guy because I got mad and didn't appreciate what he did for me....
