Your teachers are always telling you to behave like adults. I wonder if they'd
like it if you did. You may be loud and disorganized, but you're very docile
compared to adults. If you actually started acting like adults, it would be
just as if a bunch of adults had been transposed into your bodies. Imagine the
reaction of an FBI agent or taxi driver or reporter to being told they had to
ask permission to go the bathroom, and only one person could go at a time. To
say nothing of the things you're taught. If a bunch of actual adults suddenly
found themselves trapped in high school, the first thing they'd do is form a
union and renegotiate all the rules with the administration.
