“To me, the thing about friendship that makes it so singular is that it’s a relationship that’s central to our identity in that it doesn’t necessarily benefit us in any tangible way. It’s a relationship we don’t have to pursue – if we decide to stop being friends one day, nothing will happen, no one’s there to legislate or adjudicate it. It’s two people who every day choose to keep it going, and in that way it’s very powerful because it’s one you choose to work on, and you choose to without any agreement; it’s an unspoken bond.”
