The kid deserved it, the parents should teach them about Privacy.
You should have smacked the kid harder for that bullshit. I would have made a big ass scene right there on the john.
One time in like 1st grade, me and my friend were in the bathroom pissin' in the urinals. we were tryin' to see who could stand the furthest from the urinal and still make it in. We ended up pissin' all over the floor. The janitor caught us, and he was hella pissed he had to clean up our urine. So he tries to make me mop it up. But I was hella Little, I could barely even move the mop, And the janitor's just like "give me that!, get the hell outta here!"
