I do have a bit of a distinctive look, these days, with the leather hat and brown jacket. Based on a random overhearing, there's a small chance that the narrator for the ill-sited site-specific show that ran here for a few weeks worked me into the show occasionally as "Thoreau," despite my glowering at them as I left. (There were reasons. "People who love people" belted out by a lounge singer twice per day in the reading room of one of the world's most essential publicly accessible research libraries.)
Or I might have misheard. Dewey would have liked that, I think.
