When you recognize that pain and response to pain is a universal thing, it helps explain so many things about others, just as it explains so much about yourself. It teaches you forbearance. It teaches you a moderation in your responses to other people’s behavior. It teaches you a sort of understanding. It essentially tells you what everybody needs. You know what everybody needs? You want to put it in a single word? Everybody needs to be understood. And out of that comes every form of love.
