I don’t know how things were at your high school but at mine one of the top social sins was to wear jeans an inch too short. Jeans were supposed to almost touch the ground and if they were long enough that you walked on them that was okay too. Pants that were even a little bit too short were “high water pants” and if you wore them you were sure to be asked, “Are you waiting for a flood?” several dozen times that day.
Now, apparently, too short pants have become okay. Well, at least they are okay if they cost over $900. Maybe it’s just part of the Rise of the Nerds.
