Did this cause us to love our parents less? Not likely, we loved them fervently.
Then our parents would give us ten dollars to buy a Christmas present. So we bought say our mother some cheap perfume and she acted all pleased with us. We gave back to her what she had given to us in the first place, we had nothing of our own to give. Were we forced to love her or give her presents? Were we "robots" in spite of their insistence that we do their will?
