Sara," I ask finally, "what do you want from me?""I want to look at you and remember what it used to be like," she says thickly. "I want to go back, Brian. I want you to take me back."But she is not the woman I used to know, the woman who traveled a countryside counting prairie dog holes, who read aloud the classifieds of lonely cowboys seeking women and told me, in the darkest crease of the night, that she would love me until the moon lost its footing in the sky.To be fair, I am not the same man.
