1. You were (kinda?) friends in high school. You are not friends anymore.
It's OK that your dance club partner unfriended you on Facebook. If you recall, you actually kinda hated her and her show-stealing ways anyway. How soon we forget!
2. That person just has too many damn friends, and you didn't make the cut.
Listen, Taylor Swift is too busy hanging out with Sarah Hyland and Karlie Kloss and Selena Gomez and every other pretty famous girl on Earth to accept your friend request, OK?
3. You disagree politically.
Elephants and donkeys are just not compatable. Ask any zoo.
4. You said something sexist, racist, or otherwise shitty.
Hey, maybe stop doing that so you can have friends?!
5. You f*cking love swears!
Don't worry, I love your potty mouth, ya filthy sailor.
6. You post too damn much.
Maybe update about the contents of your sad desk salad every OTHER day?
7. They hate your dog and/or cat and/or kid.
Maybe the first three photos of your Siamese in sunglasses were precious, but the fourth photo made your friends turn a corner and now they hate you and your damn cat.
8. They don't care about your damn promotion.
Um, I guess if someone unfriends you because you're proud of your major life accomplishments, maybe that's a good thing?
9. Vaguebooking. Just no.
If you can't talk about something on Facebook, don't actually talk about it. If you post "OMG, I have the most exciting news but I can't tell!" then I'm gonna post an emoticon strangling another emoticon and then unfriend your vague ass forever.
10. You haven't seen each other in person in forevvvvvs.
Just under half of people who unfriended someone said they hadn't seen the person in more than a year. It makes sense. If you don't REALLY want to stay in touch, why are you staying in virtual touch? (Obviously your BFFs and mom abroad don't count. You're never getting rid of them.)
11. You "liked" Nickelback.
JK, but maybe. Probably. OK, definitely.
