Then, hopefully, they feel badly afterward.
Day before yesterday, two of my boys were playing on the playground equipment and one wanted the other to do this, that or the other thing. When he didn't respond quickly enough, the boy took Antonio's hand and arm in each hand and twisted, hard, in opposite directions.
Poor Antonio, his arm began to swell and he couldn't use it so we bundled him off to Central Hospital for x-rays and he came back with a cast!
The plus side? He is twins with Mana Sharon, who broke her wrist on a fall on a wet and slippery night! We think they should hang out together and between them, have a complete set of functioning arms!
