BUT IT'S NO JOKE, IT'S DOIN' ME HARM. I have just returned from Mother's Day in Bridgeport. I had four hours sleep last night, as I had on each of the previous two nights. As I tried to nap on the train home, a little girl five feet away tooted nonstop on a plastic pennywhistle. Please don't be too hard on anything I write from now till... well, who knows.
