xD yeah, that's pretty dumb.
my school doesn't really care about the backpacks, and we only have bag checks about.. once or twice the whole school year.
but the most dumbest ones(to me) are;
socks must be school uniform colors(black, white, burgundy, or khaki.) if you wear another color, you get a week of ISI.
no normal jackets or sweaters in class, only approved uniform jacket, or the black or burgundy sweatshirts.
yeah... not that bad, but yeah, i hate them
