Here’s one guy that you might be surprised to see in a library. On the street perhaps, or maybe in a homeless shelter, but in the main reading room of the Boston Public library? Probably not. However look again if you would please. Could it be what you are seeing is a kind of a costume? A “I don’t give a damn about what you might think of me because under this jaunty hat, I’m a fantastic writer doing research on my book of poetry that will knock your goddamn socks off.”
I love puzzles like this.
