College opens up your world to a boatload of every personality type imaginable, and some you didn't even know existed. The amount of people you'll meet in your two, four, or even 10 years of college is one of the most amazing things, and I urge you to take advantage of that.

When else can you potentially meet your best friend throwing up in the dorm bathroom on a Wednesday morning or crying at 4 a.m. over an essay due at 8 a.m. that you both procrastinated on until the night before?

1. The "Mom/Dad"

This one goes out to the savior who is basically the reason you aren't dead yet. When you wake up in your bed and have no idea how you got there, or are pulled down from roof jumping into a kiddie pool, you know who to thank.

2. The Alcoholic

10 shots at the pregame and $100 tab 5 nights a week. May drink a four loco with breakfast or regularly black on a Wednesday night.

3. The Lightweight

One shot in and they don't know what year it is. Could possibly get drunk off of smelling Amsterdam.

4. The Meet-My-Parents-Please

Another lifesaver. This is the pal you bring to dinner with the parentals when they visit to ensure that you really aren't going to die.

5. The Brains

The reason you didn't fail your hardest classes (or are doing better the second time around!!). They bless you with the notes, test prep, and anything else your anxious self needs.

6. The Talker

Great for parties, but avoid taking him/ her to the library at all costs. No matter what they promise, an hour into studying and you've successfully learned how long the tallest beer bong is.

7. The Instagram-mer

Owner of editing apps you didn't know existed, and knows how to create the feed of a current day goddess. Always asking to take pictures, and is the proud mom of your Linkedln photo.

8. The Planner

Wondering where you'll be for late nights three Saturdays from now? Ask them.

9. The Animal Freak

Cries at the thought of dead butterflies and stops to pet every dog no matter how late they'll be to class.

10. The Best Worst Decision Maker

Necessary for all spring breaks, parties, and basically any night you want to make sure the night ends memorable.

11. The Do-It-All

In short, the all around amazing person you hated in high school because it wasn't you.

12. The Napper

If they're not in class, they're cashed. Also regularly show up an hour late to any plans you have--and fall asleep literally anywhere.

Here's a toast to some of the wonderful people brought to you by the greatest years of your life.
