Welcome to college. Everything is decorated green and gold in your honor, and a new campus is ready for exploration. The dorms are the cleanest they will be all year, and there is at least one other person to meet for sure: the new roomie.

As great as a roommate from a different state, city or even school sounds, odds are you and your roommate will disagree on something. It is just bound to happen. But don’t lose hope. Here’s a list of different types of roommates that will prepare some incoming freshman and make others wish they had paid extra for that single room.

The author

This roommate is very quiet and unpredictable. Things seem to set them off, but you might not be aware of it until you find little passive-aggressive notes either stuck to the mirror, desk or random places around the room. This roommate might want their own space and might really appreciate a line of duct tape right down the middle of the floor, but they are too polite to say that. Be patient with this roommate as they might be getting used to having to share a room. Try to make them open up a little, and make sure they know they can talk to you about any problem.

The obsessive cleaner

This roommate really hates a dirty room. They will probably empty the trash several times a week and might have a cleaning schedule posted somewhere in the room. They might get agitated if your side of the room isn’t clean and picked up, but know their heart is in a good place. And really, who doesn’t enjoy a clean space? Go along with it and maybe create some new cleaning habits from it.

The party animal

This roommate always seems to be gone, and they always seem to be coming from some sort of gathering down the street or across town. They typically come back around 3 a.m. and sleep until the late afternoon. Just keep this roommate safe, and make sure they check in, and get help if they don’t.

The slob

The complete opposite from the obsessive cleaner, this roommate really doesn’t mind living among their clothing on the floor, the trash can overflowing and a slight, stingy scent in their room all the time. Make sure to talk to this roommate if you prefer a clean space, and remember that everyone has different preferences for how they want their room to look. Communication with this roommate might just save your year.

The hermit

This roommate NEVER leaves the room. They usually have Netflix open on their computer all the time, they bring their meals back with them and they are perfectly happy just staying in the room. If you feel inclined to invite them to dinner with your friends or spend some time on the intramural fields, do it. They might just be uncomfortable meeting new people.

The one who’s never there

Like the party animal, this roommate just seems to never be around, but it might not be because they’ve been surfing the social scene. They might just be involved with a lot on campus or working all the time. No one knows how they effectively get anything done for their classes, but they do check in every once in a while, usually when they need to brush their teeth, shower or write that final paper.

The mooch

The mooch is the roommate everyone dreads. You’re not too sure if they actually own the things that are on their half of the room, or if those are just borrowed things your roommate forgot to return. If you happen to be someone who really doesn’t like sharing, let your roommate know.

The night owl/early bird

Everyone has their own sleep schedule, but if your roommate likes to stay up late and you like to get up early, there could be some tension. Don’t make them change their habits. Just create some rules so that everyone gets the right amount of sleep when they want it.

The athlete

You swear the only thing your roommate owns are running shorts, t-shirts and sneakers. They constantly seem to be going to the gym and have a protein drink every morning after they’ve returned form the rec center. This roommate might make you feel a little lazy. But on the bright side, you usually have the room to yourself while they are at the gym all the time.

The best friend

Perhaps you have lucked out and you have the perfect roommate. You are both best friends after the first month of school and feel comfortable coming to each other when you need help. You both have similar interests and some of the same preferences on how to run your room, and you leave each other cute little notes of encouragement all over the place. Congratulations! You both, however, cannot wait to get out of that little dorm room and into an apartment next year, but you already have your roommate situation figured out.
