I can't believe how well the surgery went. I feel like a new person.

I'm so happy to hear that! The doctor said the heart was a perfect match, right?

Yes, it was. I feel so grateful to have received the transplant.

You should be. It's amazing what modern medicine can do these days.

Absolutely. And it's all thanks to the donor who gave their heart. I hope their family knows how much I appreciate it.

I'm sure they do. You've been taking good care of yourself since the surgery, right?

Of course. The doctor gave me a whole list of things to do and not to do. I'm following it religiously.

That's good to hear. I want you to be around for a long time.

Me too. And not just for me, but for you. I want to spend as much time with you as I possibly can.

You're going to make me cry.

I know, and I'm so grateful. You're my whole world.

And you're mine. Hey, remember those meatballs we made a few weeks ago? They turned out pretty good.

Hey, I thought they were pretty tasty. But seriously, thank you for being by my side through all this. You're my rock.

I'll always be here for you. And I'm just glad you're feeling better now. That's what matters most.
