In high school, you have the preconceived idea of how roommates work: pillow fights, long talks about cute guys, the latest gossip about your mutual friends, late night Sonic runs or movie nights and etc. While some of these things do happen, here are the 10 biggest things I learned while living three miserable years with roommates.

1. Girls are mean!

I realize that sometimes girls get on your nerves, and while sometimes emotions and hormones get the best of me, some girls are just straight up petty and really mean.

2. Mean girls have even MEANER moms.

I'm 100 percent sure my last roommate's mom was Satan's mistress. My roommate wasted no time calling mommy to resolve her issues and even gave her mom my phone number!

3. Do roommates even know how to clean?

Obviously not; my last roommate called her mom to come weekly and do her cleaning.

4. Your roommates clothes have been sitting in the dryer for a week.

You know the second you touch her clothes it's going to be war. So you opt for hoping you can make it through the rest of the week on what clean clothes you have left and hope you don't have to resort to washing them in your bathroom sink and drying them over the shower curtain.

5. *said roommate isn't supposed to have a dog*

Roommate still has dog. A dog that poops, sheds and throws up on the stairs. But don't say anything about it because that pomeranian who needed a bath and a haircut a month ago is practically royalty, and anything said negative about it is treason.

6. You come home after a long day just wanting to lay on the couch and relax...surprise you have a living room full of LOUD, OBNOXIOUS sorority girls.

I'm not downing all sorority girls, this particular group just didn't seem to realize my little house wasn't the Delta Apple Pie house. NEWSFLASH: you have your own home, GO TO IT!

7. Yes, I have a boyfriend. Yes, he will be at the house. No, I'm not 12; I'm 21.

My last roommate's mom (and roomate) still lived under the impression that boys had cooties. My roommate would text me saying he was around too much (she had company everyday), and her mom always had something to say about it as well. NEWSFLASH: we are all adults here and dating is part of college.

8. DO NOT, I mean absolutely do NOT live with random roomies.

I wish someone had told me this; I could have eliminated 99 percent of my problems if I hadn't been matched with "random crazies."

9. I definitely didn't open that case of water and drink five in the last 30 minutes.

Oh wait Delta Apple Pie queen and her "sisters" helped themselves to it. AGAIN!

10. The BIGGEST lesson that I learned was that the extra $50 a month for a one-bedroom apartment is a well-worth-it investment.

Seriously, save yourself the trouble and just get yourself your own apartment.
