I would never wish cancer on anyone...except the person who broke into my car on Christmas night. The car window that was broken cost more than the stolen items.
This perp stole a broken satellite radio (I was about to buy a new one), a bunch of CDs that no one would want (I'm weird, so I had Air Supply, Celine Dion, Elvis, and a bunch of home-made ones), some clothing (scarf, hat, gloves), and about $3 in change.
But the criminal left behind the $100 sunglasses and $300 softball bat in the trunk. Smart guy!
If my wish comes true and he does get cancer, I wonder if that crap he stole would pay for his chemo treatments. My guess is not...
