There comes a time in most people's life when you have to do adult things and learn adult subjects. These adult things happen in a magical place called college. College is that one place where you can be free to do whatever you want, whenever you want (except for finals week.) But how can you tell if someone's in college or not? If you aren't sure, take these top 11 tips to help you spot a college kid.

1. The Hoodie

If you spot a teenager wearing a hoodie with a school logo on it, chances are that they actually go to that school. But beware of the posers wearing hoodies like this. Or the "football fan' hoodie.

2. The Eyes

College kids who have completed 3 years or ones that have only just started their college career all have the same look in their eyes. It's the look of all of the hopes and dreams that they lost once they entered the world of college. This look is very real. If you can't seem to identify this look, wait until the week of finals. That's when the look is the most visible.

3. The Conversation

Step 1: Start talking to the person. Step 2: Ask them a college related question. Step 3: Listen.

"So are you in college now?" "Yeah, I absolutely love/hate it...blah...blah."

"What do you think about this climate change?" "Well, you see, I'm a Environmental Engineer major and I believe that...."

"Want to go out to dinner?" "Are you paying?" (refer to #2)

"What do you want to do for the rest of your life?" "Pass college."

4. The Speed at Which They Arrive to a Location of Free Food

Let's be completely honest here, college kids thrive on the offer of free food. Taco Bell is offering a free taco for two minutes on a Sunday night? They'll be there. Work parties that provide catering? They'll be there too. Literally anywhere, anytime. If you provide free food, they will come.

5. Ask Their Age

They're 21. End of story.

6. Go to the Library

I promise you, on any given night, there will be college kids at the library studying or sleeping. Or using the free internet or printing.

7. Smell Them

Actually, maybe you shouldn't. Half of them can't afford to do laundry and the other half are too busy studying to remember to shower or put on deodorant. They apologize. But until loans cover laundry costs, they must reuse their pants for weeks. Or months if they own Febreeze.

8. Call Them Before Noon

If you call and they don't answer, they're asleep. The only reason that they'd be awake before lunch, is for classes, exams, work or because they never fell asleep in the first place.

9. Food

If you ask what they eat and they answer pizza, ramen, or microwave foods, you may be talking to a college student.

10. Observe Them

What are they wearing? Do they have rain boots and an umbrella on hand? How about their hair? Does it look like they just rolled out of bed? Do they have makeup on or no? You can tell a lot about a person by how much they effort they've put in to their look. Or for a college kid's sake, how little effort they've put in.

11. The Bars

If they're ordering the vodka red bull, the trash can, or any other random cocktail, they're a college kid. If you see them getting a natural light from behind the bar, you've cornered them.
