Draw a circle.
I found this sheet of math equations in the street while walking the dog around the block. It reminded me that later drafts of my “frist novel” were titled: To Walk A Circle. It was more or less about walking around all those etoilles they have in Paris that get you so lost sometimes and there is no grid by which to dead reckon your way home. Instead you go from L’Opera and walk for thirty minutes and somehow end up exatly again at L’Opera. Last time I was in Paris, I had one entire foot (my gimpy right one) turn into an enormous blister… the whole foot, one blister. For the next week I hobbled around Paris like Ratso Rizzo: Je promenne ICI! I thought it was a grand metaphor for life. Now it sounds a little pretentious, but it does explain Arc Along the Watchtower as a title too.
