“I suppose I could spend time theorizing how it is that people are not bad to each other, but that's really not the point. The point is that in almost every instance of our lives, our social lives, we are, if we pay attention, in the midst of an almost constant, if subtle, caretaking. Holding open doors. Offering elbows at crosswalks. Letting someone else go first. Helping with the heavy bags. Reaching what's too high, or what's been dropped. Pulling someone back to their feet. Stopping at the car wreck, at the struck dog. That alternating merge, also known as the zipper. This caretaking is our default mode and it's always a lie that convinces us to act or believe otherwise. Always.”
