--This kid is one of the most popular kids in school, --
Sticking candy up your nose in front of the class is the way to popularity in hight school now?
They're just teenagers. Clowning around is typical for that age. You know, straws in the nose, squeezing mashed potatoes out of your mouth.
It is the damned adults acting a whole lot more juvenile by making major productions of normal adolescent behavior that is the real problem. They take *every little thing* and make a BFD out of it.
With kids, especially teenagers, you pick your battles. You don't issue ultimatums over everything. Guaranteed losing approach.
Besides, the issue here is the principal's actions, not the kid's.
That, or promiscuity
I know a kid who can actually stick his tongue up his nose. I'll have to ask him how well that works when trying to impress the young ladies.
