Ursula K. Le Guin said this quote

I have told the story I was asked to tell. I have closed it, as so many stories close, with a joining of two people. What is one man's and one woman's love and desire, against the history of two worlds, the great revolutions of our lifetimes, the hope, the unending cruelty of our species? A little thing. But a key is a little thing, next to the door it opens. If you lose the key, the door may never be unlocked. It is in our bodies that we lose or begin our freedom, in our bodies that we accept or end our slavery. So I wrote this book for my friend, with whom I have lived and will die free.
