"I am convinced that people have invented the idea of love." Tom ignores him. "They convince themselves that they do not want to be alone, and each relationship a human forms in attachment is an attempt to fill in the emptiness in one way or another. A person could make you feel needed for example and you are more likely to spend your time with them, someone could seem to want to take care of you because by doing so you will take care of them. You say you did all of it for love so prove it."
