The postman cometh

It's raining a bit (glad for the tarp) and I am following the postman's progress by the sounds of the barking neighborhood dogs. As in all neighborhoods, the daily arrival of this stranger is a pivotal event. Our current postman wears either headphones and listens to his tunes, or a headset and talks on the phone. It is a little disconcerting to wake up from a nap to someone having a conversation on your porch-and what on EARTH does he talk about all day?
