My dad had pocket watch that he never used and that I sometimes played with. I damaged it somehow, possibly broke the glass, but I can't remember the exact damage, but I do remember hiding it under an armchair in panic, hoping it wouldn't be found and that it would be forgotten about. Eventually it was found and I did get a bollocking.
I also ripped the handles off the living room door by swinging on them. They only had piddling little screws in them, but I didn't know that at the time. Luckily my dad was able to screw them back on into undamaged bits of the door, covering the damaged screw holes, and I was banned from swinging on them.
My son broke one of our living room doors when he was in his teens and Mrs. W and I were away for a few days. Typically, the kids had a party without telling us and one of my son's mates locked him in the kitchen. All very funny for half a minute, but when he still wouldn't open the door my son punched a fist sized hole in one side of it. It was only a shitty cheap plywood door with carboard honeycomb inside. In a panic, he asked our neighbour if anything could be done to fix it, but it was fucked.
When we got home he'd stuck a poster of Tinky Winky over it.
