"We aim to produce the best quality walnuts in the world,
and we think they are."

I have spent my entire adult life engaged in a quest to understand not just who I am but how creatures like me came to be . . . What does it mean to be born a mammal, with the emotional legacy that makes me capable of caring for others, breeding with the ovaries of an ape, possessing the mind of a human being . . . to be a semicontinuously sexually receptive, hairless biped, with conflicting aspirations and struggling to maintain her balance in a rapidly changing world?
