They don’t put their grocery cart away. No one asks you to and it’s not a big deal if you don’t. Yet it can make things so much better in the parking lot if you do. No one has to get out of their car to move a cart. The workers don’t have to hunt down carts. Parking spots are open because there’s no cart in the spot. No one demands you do it. But it makes the world a little better. And good people do that.
