IT is said that Flaubert taught De Maupassant to write. When De Maupassant returned from a walk Flaubert would ask him to describe someone, say a concierge whom they would both pass in their next walk, and to describe the person so that Flaubert would recognize, say, the concierge and not mistake her for some other concierge and not the one De Maupassant had described.
