Private sales, made not in public auctions but in one-on-one negotiations, sometimes gave a person the chance to size up his or her would-be consumer. On the one hand, if the scuttlebutt in the warehouse told you a prospective buyer lived near the place where you had heard your wife or child or parent had been sold—well, then make yourself the brightest-eyed and most compliant in the bunch. On the other hand, you might not want to be noticed in some cases.
