With all the terrible stuff that goes on around the world these days, it can sometimes be hard to see how the words "human" and "humanity" are related, but here is one thing that restores my faith in mankind:
...If a bird's nest providing shelter for a couple of newborn chicks is discovered on top of a train station sign - right in front of the ticket machines no less - we don't climb up there and dispose of it. Rather, we let them mind their own business and put up a big notice warning people to "watch their head".
