1. McDreamy’s hair.

...and his eyes, and his smile, and his everything.

2. The way Alex looks at Izzie.

We can't help but want them together, just look at them, they're perfect in their own twisted and overly-complicated way. #TeamKarevens

3. Cristina’s humor.

No one does funny like Cristina. She's the comical sceptic, and we can't help but love her.

4. Cristina’s breaks in character.

They don't occur often, but we live for these moments of exuberance. Yang is just like us.

5. McDreamy and McSteamy’s bromance.

Who knew these two could rekindle their long-lost friendship after countless fights, sucker punches, and relationships gone wrong. They're brothers, and we love them.

6. George’s family .

You can't help but join in every time you hear their synchronized, brotherly greeting, "O'MALLEY!"

7. Bailey’s motherly advice.

She may be harder on the interns than any of the other attendings, but she cares about them as if they were her own children. We see you, Bailey, and we love you.

8. Izzie's selflessness.

The girl was handed a check for $8 million, and left it on her refrigerator for weeks until deciding to spend it on surgeries for patients who couldn't afford them. She then donated the rest to open a free clinic named after her deceased fiancé. Izzie Stevens, you are a star, and you inspire me.

9. Denny Duquette’s smile.

Even in a hospital bed, the man remained optimistic and beautiful.

10. Alex's sentimental moments.

Oh, Karev. We're alway rooting for you, even when we hate you, we're secretly rooting for you.

11. Cristina and Meredith’s famous line:

“You're my person.”

12. That time Richard dyed his hair, "...for the ladies."

The man was going through a mid-life crisis, therefore, no judgement.

13. Addison’s impeccable wardrobe.

Addison shows up to Seattle Grace ready to work in her satin pumps and pressed pin skirts on the daily. Forget the scrubs, she's always on her A-game.

14. And the one episode Addison wasn't dressed to kill.

Yes, Addison. We feel you, girl. We are you, girl.

15. Lexie, just Lexie in general.

She's Meredith's adorable, loving younger sister. She's got all the brains of a Grey, with a sense of refreshing innocence and eagerness, somewhat resembling Izzie. How can you not love her?

16. The late-night talks at Joe’s bar.

Ah, so many revelations, and so, so many shots of tequila.

17. Burke and Cristina’s relationship.

They were the perfectly dysfunctional, barrier-breaking couple -- we couldn't not love them, you know?

18. That time Cristina lost her eyebrows.

Mama Burke knows best.

19. Callie’s sarcasm.

She offers that refreshing punch of comic relief we need ever so often throughout the hectic, crazy episodes.

20. The brutal honesty and relatability.

Ah yes, I totally relate to these multimillionaire doctors, and arguably supermodels, so what I can conclude from all of this is that I am destined for success.
