All teachers have those little things that drive you INSANE during the course of the school year. Initially for me it was the constant need to get up and use the pencil sharpener...ugh! (or worse yet...not having a pencil...nothing slows down notebooking more). I made my peace with that years ago by having a pencil loaner bin filled with the cheap plastic pencil sharpeners (that catch shavings). I buy those at Staples during their penny sale and as a teacher you can get more then the "four per customer" rule. I did not buy enough for this years class and made a mental note to get more. Make sure you put your name on it with permanent marker THEN put a piece of clear tape over it. That has kept them from disappearing and is an easy way to tell the difference between yours and a student. Of course my next little pet peeve is that students will not take a pencil if it doesn't have an eraser so that leads to a 5 minute search through the pencil loaner bin for one that does.
