See, my school just does not care about anything, admittedly, no one has ever shown up wasted, or been so bold as to put a hood up, but if they cracked down on dress code, more than half of the girls would be sent home for either too-short shorts, or exposed midrifts. And forget phones, I have seen people checking IG or FB or other social media while a teacher is lecturing. Btw, I'm at a highschool, and the classrooms are no more than 20x20 ft
