In the arcade you don't keep moving, as you would in the farmers market stall, from commercial bit to commercial bit, but you linger. We don't like lingering. HUD proposed a couple of weeks ago to prohibit smoking in public housing. Seriously? I mean, it was one thing to outlaw smoking inside—even when I was a smoker I came to like having to go outside—but when you outlaw smoking outside, you are actually outlawing congregating, lingering, loitering. In the days before cellphones smoking was so useful in a new city because you could stop and mask your lostness with a cigarette.
