"I want nothing from you except what you wish to give me. I want you to come to me seeking nothing but your own enjoyment. To know that the joy you give me is paid for by the joy you get from me – not by your suffering or mine. I don't accept sacrifices and I don't make them. If you asked me for more than you meant to me, I would refuse. If ever the pleasure of one has to be bought by the pain of the other, there better be no trade at all. A trade by which one gains and the other loses is a fraud."
from Ayn Rand's "Atlas Shrugged"
