In Naples, lonely people leave their homes early in the morning. You can tell they're lonely by the look in their eyes. Mostly men, often walking a dog, typically mixed breeds that look as scruffy as their owners. You see them heading to the coffee bar, chatting with the newsstand owner, buying cigarettes, timidly interacting with each another.

This morning as I was going to work, I tried to put myself in their shoes. I woke up tired and moody, but as soon as I left the building, I felt compelled, like every day, to say to dozens of "buongiorno!" (good morning!) and smile in return just as many times.
