You know that episode of The Office where Michael finds out Toby's back, so he reacts like this?

We all have that one kind of person that's our own Toby. Here's a list of some of the ways you can be one of them!

You are the worst person if:

1. You chew with your mouth open.

Oh. My. God. This one is self-explanatory. In fact, if this doesn't make you mad, that means you probably do it too.

2. You look at people’s screens while they’re texting, internet surfing etc.

You don't need to see that I'm telling my mom about a super cute dog I saw on the street or that Ann Davis's daughter got sick at school today because it's flu season. Text your own mom and friend Ann Davis on Facebook.

3. You start swiping right or left when someone gives you their phone to look at a picture.

This is one of the biggest invasions of privacy ever and you need to stop. Immediately.

4. You ask your friend, “You’re gonna eat all of that?”

Whether you are trying to mooch or judging them, you're awful. If you get it, you intend on eating it, clearly, so let them live.

5. You tell someone where you got a clothing item that they just complimented … without them asking.

"Omg, I love your top!" "Thanks! It's from the Marc Jacobs exclusive collection in the color eggshell."

6. You tell someone you dislike their music taste.

A pure insult. Keep your opinions to yourself please. I like my music. I like One Direction from 2012. If you don't, I'm sorry, but that's not my problem.

7. You turn every conversation to talking about you.

If you hijack a conversation that had no intention on being about you (or worse, you change it to fit the thing that you wanted to talk about to include yourself), you need to let other people have a chance. Not everything is about you all of the time! I'm trying to hear about how my friend taught kids in Africa English, not how you one time touched Dwayne "The Rock" Johnson's neighbor's pet shih tzu.

8. You say the phrase, “If you don’t tell me what you got on your test, that means you didn’t do well.”

SIR, PLEASE. Whether I did or didn't do well is none of your business.

9. You start packing up while a professor is talking in a lecture/before you are dismissed.

Hi, yes, I'm still trying to listen. They're trying to teach. Don't be rude.

10. You don’t cover your nose/mouth when you sneeze/cough.

Gross. If I get sick, I'm sending you my doctor's bill.

11. You listen to your own TV show/music without earbuds while people are trying to have a conversation.

Look, I'm all about everybody listening and watching whatever they please. I don't judge. However, if you want to watch the Patriots, that doesn't mean we all want to watch the Patriots as well. You can either grab earbuds and come in the common room or watch it in your dorm room.

12. You jiggle the bathroom doorknob without knocking first.

This is just an accident waiting to happen. Save both of yourselves the embarrassment and knock.

13. You only like to talk about politics.

People have different political views. That's life. This conversation will not end well for anybody involved, so just keep your opinions to yourself and don't disrespect others if they're different from yours.

14. You make fun of me for calling my mom.

First of all, I love my mom. Second of all, you're obnoxious. Third of all, sounds like you should call your mom so she can tell you to stop being annoying.

15. You whisper something to a specific person while people are around you.

This is why I hate nail salons. It's the same feeling of "You may or may not be talking about me, but either way, I feel like you are". If you have to tell someone something that badly, wait until you two or either alone, or text it to them.

In the future, try not to do these things. You're either being pretentious, obnoxious, or rude -- none of which are good things to be :)
