Now or Never

Meredith: No, you know, let's go. We gotta go. We gotta run to city hall, we'll come back, you'll check on Izzie, we'll monitor John Doe. I'll go talk George out of joining the army.
Derek: Look, we could do this another day.
Meredith: There is no other day! Every day is like this! Every day there's a crisis! There's no time!
Derek: Meredith.
Meredith: I love you and I do want to marry you today. But, there is no time.
Derek: Do you have a piece of paper?
Meredith: For what?
(...)
Derek: I wanna be with you forever, and you wanna be with me forever. In order to do that we need to make vows. A commitment. A contract. Give me a piece of paper.
Meredith: I don't! I... I... I don't. I have post its!
Derek: Ok. What do we wanna promise each other?
Meredith: That you'll love me... even when you hate me.
Derek: To love each other, even when we hate each other. No running. Ever! Nobody walks out. No matter what happens.
Meredith: No running.
Derek: What else?
Meredith: That we'll take care of each other, even when we're old, and smelly, and senile. And... if I get Alzheimer's and forget you...
Derek: I will remind you who I am, every day. To take care when old, senile, and smelly. This is forever. Sign.
Meredith: This is our wedding. A post it?
Derek: Mhmmm. If you sign it.
Meredith: Now what?
Derek: Now I kiss the bride.
Meredith: Married.
Derek: Married. You see that? Plenty of time!

Meredith: Doctors spend a lot of time focused on the future, planning it, working toward it. But at some point you start to realize your life is happening now. Not after med school, not after residency, right now. This is it. It's here. Blink and you'll miss it. (...) Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow.
