Everyone has pet peeves when it comes to what other students or teachers do in class. If you're really unfortunate, a teacher or student will commit to doing this throughout the semester and might make you loathe the class. Over the years I have come to realize what some of my biggest annoyances are when it comes to the classroom, and I'm sure other people have experienced some of these as well.

1. When students bring smelly food to class,

This is just mean. We're all trapped in this classroom together, and there's nowhere for the smell to go, please just eat it before the class or in the hall.

2. When someone pushes down on their mechanical pencil and it makes the awful squeaking sound.

Why don't I just run my fingers down a chalk board while we're at it?

3. When the professor holds you after lecture to take attendance.

And always seem to drag it out.

4. When a professor cancels class, but you don't find out until after you walk all the way there.

You don't need to leave a note on the door, we have email for a reason.

5. When you get paired with people in group projects that bring literally nothing to the table.

I guess I'll be doing all the work, yet again.

6. When the person next to you always asks to borrow something.

I didn't buy these pens and this notebook for you to take from me every class. Figure it out.

7. Having class on Fridays after 2 p.m.

Or at all, for that matter. Can this just not be a thing?

8. When other students have a private conversation during the whole class when you're actually trying to pay attention.

Dirty looks never work, and the prof always seems to never notice or just not care. Ugh.

9. When profs announce that they don't allow laptops in class.

No.

10. Having a know-it-all in your class.

Please put your hand down, or better yet, stop interrupting the professor. You're taking this class for a reason; you don't know everything.

11. When someone decides to switch their seat halfway through the semester.

Seriously, WHY do people do this? You pick your seat by the third class and you commit to that for the whole semester. You're throwing the whole classroom dynamic off when you decide to switch. I feel like someone always takes my seat on exam day. Just please stick to your seat, please.
