After 5 years in college I have filled many a notebook with "notes". My mind wanders about 4 minutes, on average, into every class and I end up drawing or writing down things that have nothing to do with class. For example, in Biology 101 when I'm sure we were talking about evolution or cell division, I wrote this:
"The guy sitting two rows in front of me has a buzzed head. The back of his head has a lot of wrinkles. It looks like a frowning baby. This baby is pissed. I assume the baby is pissed because his face is no longer protected by hair, and it's a blustery one today.".
