We did NOT do this kind of thing at our dances, even in high school. You'd be kicked out of the dance for acting this way.
Did we do things out of the view of adults, well yeah. That`s the point, we were smart enough to hide it, these kids clearly don`t care.
Also, at 13, you have no F`ing clue what your talking about, I know you think you do, but in another 12 years or so you realize you knew jack poo about anything.
