Her

You asked me what my favorite color was.

I said "The color of your eyes" because when the sun hits it just right, I can see a galaxy in them.

You asked me what my favorite book was.

I said "Whatever book your reading" because if there is a text out there that can capture you and your wild imagination, it's a miracle book.

You asked me what I want to do with the rest of my life.

I said "Spend it with you" because who could want anything more?
