Look, you have dumb 13 year olds who would do that. The kind of kids who's username is littleprincessbitch123, sometimes they drink alcohol to be cool. Dumb ones. And you have the normal/smart ones, who will not try this because they actually listen to their teachers. The ones who are online, being nice, who you don't suspect to be so "young" because they behave more mature. So don't think you can just judge people on their age, because that's bullshit. (and if you want to know, I'm a 14 year old girl, who doesn't judge people on their ages or race or apperiance.)
People are forgetting, being 10/11/12/13 isn't exactly being a little kid anymore.
