Kids can be such little bastards. Though your son's bully has funny timing, considering the entire internet was abuzz about peanut allergies and allergy-based bullying about two days ago. I think the bullies ought to have their lunches limited by whatever allergic ingredient(s) they tried to use against their victim... and have the teacher search their lunch every day to make sure. Kind of a combination "walk a mile in their shoes" and public embarrassment deal.

*hug* Wow, you had 22 excess ccs of fluid in your knee? No wonder you need drugs. I hope you feel better!
