Reading.
Not that Lee had a certain prejudice against books or anything, but why would she spend endless hours looking at dead trees when she could fire up her laptop or go outside and look at real trees? Truth be told, Riley used to be such a reader, but all hell came down when she first sighted Natural Geographic and all the world had to offer. Like laptops and binge watching The Vampire Diaries? Obviously Hogwarts didn't appreciate the art of laptops because they - nor any technology for that matter - worked. It was depressing that the only entertainment they had to offer were a bunch of dead trees with pretty covers.
But Riley found herself slumped in the miserable place. She stalked around until she found a comfortable place and picked up a book and started to stare...she as stuck on one page for sevrel minutes, trying to understand something, and it must've been really weird, seeing a random twelve year old stare at a single page for a really long time. Unfortunately that was Riley. She also had a distant thought, thinking about whether or not she should contact the head of her house on a proposal to fill the library with laptops.
