Don’t get me wrong, I’m not trying to claim my way is the only or even the best way! A thousand debates have been had over the “correct” Cosmere reading order, and I personally think there is basically no “wrong” order.
I’ve just found that the people I know who started with Mistborn, often struggled to get into Elantris and/or Warbreaker. I don’t think it’s unfair to say that they are not as breezy a read as Mistborn. And that telling them “it’s a shared universe! You just gotta read these two other 600-page books before that starts mattering” is kind of a hard sell.
As far as I can tell, the “problem” is that the dresscode states that the student’s hair can’t extend below his eyebrows or ear lobes “at any time”. So, hypothetically, if this student took his hair down out of the braids, it would be longer than the dresscode allowed.
This, of course, is fucking stupid reasoning. The school probably just doesn’t like this hairstyle - because racism - and is choosing to use an overly literal reading of the rule to try to force the student to change it.
