Arrive at your own conclusions.
I wish you well,
How that would have pleased me, your anger, your hatred, your misery, your frustration, your suffering, until, of course, eventually, perhaps years from now, in the arms of some master, a leather worker, a peasant, a sleen-breeder, your last psychological defenses would shatter and your womanhood, released, would cry out and claim you, reducing you to the welcomed, surrendered abject glory that is the right of your sex.
