The Thumbtack

Today my 11yo needed to clean his room so he could have a friend come over tomorrow.  He shares a room with his 9(almost 10)yo brother, so although the brother wasn't having a friend, he also needed to clean his side of the room.  While the 9-almost-10yo was cleaning, the 11yo stuck a thumbtack in the bottom of his brother's foot.  While the offended brother cried, the 11yo stuck the tack in his own heel and said, "See? It doesn't hurt! Quit crying!"  The dummy that he is didn't realize I was right outside the door and heard everything.  His punishment was to have the entire room clean, including his brother's half, within one hour or he would have to "grab his ankles."  For those who don't know, "grabbing your ankles" means bending over and getting the strap! The room got clean and the brothers made peace.
