Fermat's Principle of Least Time
So I pay close attention, and note every detail.
From the beginning I knew my destination, and I chose my route accordingly. But am I working toward an extreme of joy, or of pain? Will I achieve a minimum, or a maximum?
These questions are in my mind when your father asks me, “Do you want to make a baby?” And I smile and answer, “Yes,” and I unwrap his arms from around me, and we hold hands as we walk inside to make love, to make you.
