When I was a kid, I got in trouble for something big (don't remember what) and my mom threatened to not let me go on vacation with my grandma, which was happening in a week from that day. I was so pissed, I kicked a hole in the wall the size of my foot. I was afraid I'd get into more trouble and for sure wouldn't be allowed to go, so I pushed a bookshelf in front of the hole. There, it was hidden for three years before my mom decided to get my room painted. I showed the painter the hole and he patched it up before painting over it and he never told my mom. I totally got away with it.
