I NEVER wish for anyone to get injured, and it has nothing to do with being self-righteous. As someone who has had several ankle, knee, and leg injuries, I know how agonizing and painful they can be, and how long the recovery process can take. In fact, a few of my injuries still affect me today, and probably always will. Once the cartilage goes, it doesn't come back.
I couldn't imagine ever being any bit excited to see anyone get hurt. When I see someone get injured, it usually sends a shiver down my spine, and makes some of my previous injuries hurt.
