My DVDs are in alphabetical order, and my books are alphabetical by genre.
I hate it when people chew with their mouths open.
I don't like when people eat near me. I hate the sound that chewing makes, that wet kind of noise.
I have an inability to doodle because my drawings need to be thought out and I can't draw with no idea of where its going.
Each of my school subjects has a different binder and the notebooks and binders are colour-coordinated. As are my highlighted notes (pink for definitions, blue for conclusions, yellow for statistics or figures, etc).
Everything has to be parallel or at right angles.
I follow my morning routine very strictly, right down to what order I wash my body parts.
None of my food can touch on my plate.
I don't eat blue food.
I brush my teeth for the duration of the song "Breaking Dishes" by Rihanna, cuz its long enough that my teeth feel clean but my gums don't bleed.
When a friend borrows my books, I give them to him or her in a plastic bag and I have rules... they must wear gloves while reading the book, they cannot eat or drink anything while reading the book, cannot read it in the bathtub, must use a bookmark (no dogears), and they must use two hands while reading it (so the spine doesn't crack).
I keep my books from the library in piles according to when they are due and whether or not I have read them yet.
Despite all this, my room still has clothes all over the floor. XP But I never sleep in shirts with screenprinting cuz the design cracks and gets all stretched out.
My clock is nine minutes fast so I can press the snooze button and still get up on time, and also then I am never late for something if I am in my room.
I actually have OCD (with medication and everything), so this is just an inkling of my obsessive-compulsive habits XP
