Oh my dad, bless his heart...
When I still lived with my parents, he took it upon himself to clean my dresser top. I will be the first to admit, it looked like a small tornado had gone over it, but to my teenaged sensibilities, it was organized chaos. The earrings weren't in the earring drawer, but I knew exactly where they were. Same with the hairbrush and barettes, lip gloss, etc. I was mad for a week after he did that, at least until I had located most of the stuff he had so helpfully "put away". BUT, I understand that it was his house, and he did have a right to do what he did. (Although it was so "counter-helpful" to me that I literally had to re-purchase some items that I could. not. find.)
Cue to current day, my DF (now DH) and I had recently purchased a house, and we got a dog. My parents would occasionally come and pick up our dog while we were at work, to take him to the off-leash park with their dog. This part was SUPER helpful, as it meant we did not need to walk him after work and could just relax. But one day, dirty dishes had gotten away from us, and there was a sinkful, as well as a pile on the counter awaiting washing when we got home that evening. Upon dropping off our dog, my dad washed every single dish he could find out in our kitchen. Well, I got home and lost my mind. I KNOW he thought he was being helpful, but to me, it was a gesture saying "If you kids are too darned irresponsible/lazy to keep up with your dishes, I guess I'll just have to let myself in and do them myself." I had words with my mother, and it has never happened again.
Size 11 ladies shoe here, I guess you have to expect your toes to get stepped on once in a while
(For the record, my dad is one of the greatest men I know. He really, honestly, wants to help, anyone, anytime he can. He's just a bit misguided occasionally. Also for the record, I am as stubborn as a mule
