How can you not love them to pieces?

As I was tucking Griffin into bed tonight he grabbed and kissed the back of my hand and said "mom, I love you...you are my best friend...you are my love, right?" Then he went on to say how sad I would be if he "got runned over by a car and got bleeding and died." How can you not want to snuggle up to him all night. These are the joyous moments of motherhood.
