When it comes to parental alienation or grandparent alienation, we walk around with the overwhelming emptiness of a child's absence while carrying the heaviness of their sweet and irreplaceable memory...

I never imagined a love so pure, nor a hate that could be so cruel.

Adolescent alienation is going to find a sympathetic ear in Thoreau.

The people of your culture cling with fanatical tenacity to the specialness of man. They want desperately to perceive a vast gulf between man and the rest of creation. This mythology of human superiority justifies their doing whatever they please with the world, just the way Hitler’s mythology of Aryan superiority justified his doing whatever he pleased with Europe. But in the end this mythology is not deeply satisfying. The Takers are a profoundly lonely people. The world for them is enemy territory, and they live in it like an army of occupation, alienated and isolated by their extraordinary specialness.
