frankly, that's not even strict to me. want to hang out after
school? go home and get changed first.
there is a reason why it is called a uniform. it was meant to be
worn that way, if you want to wear it any other, it wouldn't be
called a uniform.
freedom? the kids have all the freedom in the world. what other
freedom do they want?
how would they like living in a time where there was a curfew for
the whole country? when there were no malls, no public transport,
etc etc.
the least they could do is to maintain some discipline and order in
their lives. either they do that, or they do this saying "do what
you want, just don't get caught".
