I don’t consider myself a chickenshit, but it’s been a long time since I actually enjoyed being on a roof. Not, “Yes, isn’t this a lovely view, now get me the hell down from here,” but, “I want to stay up here forever!”. Hey, there was a time . . . My father once fell backwards off a roof while shovelling snow. Needless to say, since there was enough snow on the roof to warrant shovelling, he landed in a big pile of it and only knocked the breath out of himself. I don’t mind ladders or heights, I just have a natural aversion to full body casts: they itch.
