The bingo caller was small and quick, a wisp in pork-chop corduroy, wearing duck boots of all things. You want a bingo caller to be heftier, heavily lipsticked, cloudy-haired. Animal print and costume jewelry, something like that. But this was just a sliver of a girl, blitzing through numbers, leaving no pauses for conversation or even idle thoughts. A tightly-delimited bingo night, this one.
