1. Let's start with the time Meredith was all coy, trying so hard to resist McDreamy.

2. And then when Meredith shoved all of her doubts and insecurities behind and stood up to her man.

WERK IT MER.

3. This giggle-fest that is forever stamped on our hearts.

4. Every single moment that Derek said something cute/weird like this.

Like, okay. Sure. Take a bite.

5. The time Meredith got really real for a sec.

6. We'll never forget family tea party of our dreams.

Take a second to appreciate Meredith's tiger ears.

7. This pre-surgery kiss.

8. And this during-surgery kiss.

9. Do you remember the morning Derek woke up to find Meredith AND Cristina in his bed?

And he played it cool like a cool McDreamster does.

10. And, wait for it... this scene that made you a little *hot in the cheeks.*

11. We will never forget what Meredith said this to Derek after he got shot.

12. Or the time Derek saved Meredith and it was really, seriously terrifying.

WHY DID SHE STOP SWIMMING?

13. Take yourself back to the night Meredith made the most romantic gesture of all eternity.

14. The time Derek got all candid and serious about #MERDER's future and we squealed like a piglet.

15. And the elevator proposal that shook our insides.

16. And obviously, the post-it marriage.

NEVERFORGET

17. It was so cute when Meredith was a little panicky and Derek just wanted to love her.

OKAY have a baby already.

18. And then when Mer gave Derek the cutest daddy gift and he made the cutest face and you just couldn't take it.

19. Don't forget how perfect it was when Bailey was finally born.

20. Remember the time Derek said this?

STOP SOBBING I DARE YOU.

21. And then moment Derek chose Meredith. FOR GOOD.

22. And when Meredith made Derek promise her something serious.

23. Try to hold it together when you remember the scene where Derek said this.

the right kiss

24. Don't forget about Derek's last ferryboat ride that shattered our insides.

25. And, the final moment. The moment when Meredith told Derek it was okay.

And every piece of happiness we've ever felt was diminished.
