Listen, Grandma was only trying to HELP. She didn't want the kid to go though alot of humiliating "treatment" by strange "doctors". What does not kill you makes you stronger, and if you are a weak little boy who ends up dying from "burns" well then you were meant to, right?
Damn, I really wish I could have the chance to actually strangle someone like that, or better yet the dumbasses who stick up for them.
