21. You Constantly Have To Readjust
Glasses are supposed to be measured to fit your head. People have jobs specifically designed to do that. So why can't they ever just sit right? You question whether your head has gotten bigger or smaller or lopsided, and no matter what angle your head is at, you can be sure that those bad boys will fall down your nose make you look like that sexy librarian you always thought you were. It can also look like you're judging someone; looking over the lenses is the ultimate way to creep on what someone else is doing and obviously you're squinting because you can't see properly so instead of sexy you look like the dissatisfied, fat librarian who has to tell those kids who found out where the Human Biology section is to be quiet... again.
