I notice that throughout Paris there is a popular pairing of young folks and old. It is more then once per day that I see a young person escorting an older person through the street, listening and engaged. I don't know what this is about but I like it in a really big way. I dunno if they're related, volunteers, if they're good friends or golf buddies, if they're just walking together for that one quick moment that I see them, exchanging less than 20 words and then moving along, or waiting to steal their purses and run off quickly.
Also, when walking in the street in Paris, I keep my eyes to the ground to look out for dog doody. Often, on my way, I see dog doody in the ways of others. The thought creeps up that maybe I should shout out a warning and then the Parisians (seemingly without ever having looked down) avoid the poop with ease and suavity. Neat.
