Mr. Finstock was teaching Economics, talking to the class. Stiles and Scott were in that class,and Scott was writing down almost every word. Stiles, however, has always had trouble focusing

Stiles was trying to write down what he was saying, but kept zoning out for no reason, thinking about future plans, what happened yesterday, and more, biting the eraser of his pencil and tapping his foot. He was looking at Mr. Finstock, but his brain wasn’t really picking up or registering what he was saying.

((Stiles had ADHD, by the way. Canonically, too!!))
