You get this cool scar, and you get to miss a week of school!
Hmmm....
When my appendix ruptured they had to leave my wound open, with only a single stich in the middile of it to help it heal,. The reason it had to be left open was so that all the posionous crap could drain out. They also had to stuff i with gauze strips soaked in Daken solution, which is basically bleach water, and the gauzes had to be replaced 3x daily. It was no fun. Pluus I missed a month of work, not no silly week.

Now if your appendix was simply inflamed and removed before it ruptured you may only miss a week and not have to go through such funness....
