1. Made Our Siblings Believe They Were Adopted

I have no siblings, but I used to do this with the cousins I didn't like. Kids are stupid so it always worked. Did it work for you?

2. Hung up on a Partner

You shouldn't do this. It's bad manners and it usually makes things worse. … but it's so tempting sometimes, isn't it? Besides, there are times when the best point you can make involves hanging up the phone. It's a shame that everyone uses cell phones now, though. There's nothing quite like the satisfying crash of a landline.

3. Pranked Your BFF

This is only mean if your prank is really mean. Otherwise, it's just a weird cross between charming and annoying.

4. Borrowed Something and Ruined It

This is only mean if you ruin the item purposely – kind of. Because I imagine it still seems pretty crappy to the person who lent you whatever you ruined.

5. Swiped Your Bestie's Favorite Shirt

Bestie, partner, parent – you know you steal clothes without asking.

6. Didn't Record a Show Your Partner Wanted

If you forget, that's one thing. If you fail to record your partner's show because it interferes with one of yours, though, that's cold.

7. Lied … a Lot

Guilty. Guilty all day, every day. Jeez, I lie a lot. I need to stop that.

8. Used Every Ounce of Hot Water

Guilty. Guilty all day, every day. Sorry, Heather.

9. Flushed the Toilet when Your Roommate Was in the Shower

Or your wife. Or your boyfriend. Or your friend. Whatever. This is mean.

10. Reset Your Roommate's Alarm to Make Them Late

Okay, this is just icy. I mean, this is cold. You possibly deserve to get punched right in the face if you do this.

11. Devoured All of the Chocolate in the House

Guilty all day, every day. If there is chocolate in this house and no one else touches it in twenty-four hours, it becomes mine.

12. Prank Called Someone

This is on the more innocent end of the spectrum, but it counts. I have actually never done this. My social anxiety is so far-reaching that I actively fear someone yelling at me over a prank call. I'm lame.

13. Unkindly Forced Someone to Wake up Way Earlier than Necessary

If you do this to anyone, ever, you are the devil and I do not want to be friends with you.

14. Did Not Replace the Toilet Paper

WHAT IS WRONG WITH YOU? Oh, wait. I've done this, too. Oops!

15. Engaged in Passive Aggressive Behavior in the Break Room

Or anywhere else, really. Passive aggression is such a manipulative little mind-game.

16. Gossiped about Someone

Oh, I know you've done this. I know you've gossiped about a colleague, a friend, a mutual acquaintance – someone. Stop being mean!

17. Yelled at a Dog for Playing

Oh, I feel like an asshole any time I yell at my dogs for anything. I feel like the meanest person in the world.

Are you secretly mean, even when you don't really mean to be?
