Another thought on systemizing.
Over the past month or so, at the times when Bud has had enough, is at his limit, is as frustrated as he can possibly be, he has shouted the same thing: "But, Mama, it's UNSORTED!"
I imagine it's a script from a computer game. It's not a literal statement - he is not actually concerned about some belonging or other being all jumbled up. But the fact remains - when he's grasping for the right word to express his rage and frustration, where you or I would probably let loose with a string of curse words, the word Bud chooses is "unsorted." Fascinating.
