Greek life is where you find your family -- I mean, we're known as sorority sisters. But they're usually more than just your sisters. Here are some signs that may indicate that your Big is actually your second mom.

1. She lets me borrow her clothes.

Can’t find that white tank top you swore you brought back to school with you? Never fear, Big is here! Who needs to go to the mall when you have a second wardrobe in her closet?

2. She answers every phone call/text within minutes.

No matter the subject in question, Big is always there. And if I don’t answer my phone after a certain amount of time, she’ll make sure to send a follow-up text to ensure I haven’t fallen off the face of the earth.

3. She drives me everywhere.

The amount of gas money she’s spent driving me to wherever my heart’s desired is something I’ll never be able to repay.

4. Mainly to pick up prescriptions, take me grocery shopping, or whatever else I need.

Need a refill on your birth control and don’t have a car on campus to get it? Big will take you to the nearest pharmacy. Have a craving for chocolate chip cookies? Big will take you to the nearest grocery store, too.

5. She likes and comments on all my pictures like a proud mom should.

And no one does it better.

6. She shows me off to all her friends.

And on every social media platform. And you bet I show her off just as much.

7. She takes care of me when I’m sick.

While most people would steer clear, Big makes sure I’m okay. She’s the one who gives me the hair tie off her own head if I’ve had a drink too many.

8. She makes me laugh when I’m sad.

No boy can ever put me in the dumps for long because my Big makes sure to remind me that ugly Snapchats are much more enjoyable.

9. She makes me laugh. Period.

Usually when I’m in public so people think I’m crazy.

10. She teaches me new things.

Mom knows everything, after all.

11. Like how to "Hit the Quan."

It’s an important life skill.

12. If Big doesn’t approve, then he isn’t the one.

Goodbye, creepy boy eyeing me up at a frat party.

13. She’s honest with me.

She doesn’t sugarcoat, and that’s just what I need.

14. She lets me rant about the same thing 20 times.

I’m surprised she still has it in her to formulate paragraph on paragraph of replies.

15. She immediately knows when something’s wrong.

And sends me a text right away.

16. The "Mom Arm."

No car accidents on her watch!

17. She reminds me that she is #1.

Little is #1, too!

18. But of course, she doesn’t have to.

Big comes first, always.

19. Because my Big is the greatest mom-sister I could ever ask for.

And I’m forever grateful for that.

20. And I wouldn’t have it any other way.

Thanks for putting up with my crazy self.
