I guess I should mention that it's St. Patrick's Day—you know, in case you were unaware. This idea had pretty much escaped me until I went for a walk and turned the corner on 24th Street to find a bunch of people drinking on the street inside a pen around a bar called Dubliner's, which isn't usually the case in this quiet neighborhood on a Sunday afternoon. They looked chilly. But cheerful. Then I came back and sat at my computer.
