Sometimes, the people you live with can really get under your skin. College bathrooms are probably some of the most disgusting places on earth. And it's not because they are bathrooms -- plenty of people keep their bathrooms clean. It's because, in any group of young adults, you're bound to find at least one person who is lazy, gross, and has no respect for shared spaces.

Believe me, I've shared a bathroom with at least a few of them.

Here are the most annoying and just plain disgusting things these nasty mofos did:

1. Knocking your towels down and not picking them up

I get it if your arm bumps into my towel (or really any of my stuff!) and it falls, stuff happens. But to just leave it there and go on your merry way? Come on.

2. Leaving their stuff in/on the sink

You have your designated place to leave your stuff. Don't blockade other people from using the sink. Next time I see your crap there I'm putting it on the floor.

3. Not changing the toilet paper

Seriously, so gross guys. Especially when someone leaves their long dark hair all over the sink every. single. day. You know who you are.

5. Flicking/splashing/spitting water on someone else

I shared a bathroom with someone who would squeeze out her (very long) wet hair and drip it on the floor, and then toss her hair back so the water hit everyone around her. And someone else who would spit her toothpaste so hard that it bounced back from the sink and hit me multiple times. Literally the most disgusting thing.

6. Not washing your towels

This is the worst. And if your towel smells that much like sweat after your shower, you probably didn't really clean yourself fully. By your age, you think you'd know how to properly clean yourself. You're nasty.

7. Dripping water all over the floor (and not wiping it up)

So many people in my old house leaked water all over the floor from their showers and then just left it there for other people to slip in it or get their perfectly dry socks wet. And again: I don't know what the hell is in your shower water, but I certainly don't want it near my feet.

8. Cleaning weird body parts at the sink

No one wants to see you scrub your belly button. Please do that in private. Thanks.

9. Flushing the toilet while someone else is washing their hands (without warning)

So you can get a nice burn. It's really not that hard to announce before you flush, or at least wait until you hear the sink stop running.

And the one that really gets me:

10. TURNING THE F*ING LIGHTS OFF WHEN SOMEONE ELSE IS IN THE SHOWER.

Seriously, people. Don't do this.
