"Parenthood abruptly catapults us into a permanent relationship with a stranger, and the more alien the stranger, the stronger the whiff of negativity. We depend on the guarantee in our children's faces that we will not die. Children whose defining quality annihilates that fantasy of immortality are a particular insult; we must love them for themselves, and not for the best of ourselves in them, and that is a great deal harder to do. Loving our own children is an exercise for the imagination."
