1. Meredith and Cristina accept the fact that sometimes, it's okay not to have it all together up there.

How many times have we seen The Twisted Sisters completely lose all control of their emotions and judgement? A lot—but like Meredith says, you don't have to be happy all of the time.

2. Both Mer and Cristina know that as females, we are often judged by our looks and not our brains and capabilities.

The show is a medical show after all. We know that both doctors are kick-ass surgeons and want to be celebrated for that, not for being beauty queens.

3. They're there for each other, through the good times and the bad.

Okay, so maybe more bad has happened than good on the show, but the dynamic duo always finds a way to support each other.

4. Like all friends, Meredith and Cristina fight.

When anyone has a fight with a BFF, sometimes things are said that aren't meant. But no matter what, we're still there for each other. It may take time to come around, but we're waiting for you to come running to us when you need someone by your side.

5. With Meredith and Cristina, there is never a time that doesn't require a drink.

Who cares if it's at a hospital softball game? They certainly don't.

6. Did I mention they like to drink?

'Nough said.

7. Sometimes we all need a good snuggle buddy.

There's nothing better at the end of a tough day than to crawl into bed with your BFF. Even Derek (RIP) knows that there was always a good chance that Cristina would be in his bed.

8. They do things in unison.

Sure, it might be as simple as this little head bob, but great friends think alike. Best friends do everything together.

9. Meredith and Cristina have mastered the art of dancing it out.

Need to let go? Dance it out. Need to celebrate? Dance it out. Cue the Tegan & Sara.

10. You're my person.

Everyone needs a person—go find yours.
