Once when Aesop happened to be the only slave in his master's household, he was ordered to prepare dinner earlier than usual. He thus had to visit a few houses looking for fire, until at last he found a place where he could light his lamp. Since his search had taken him out of his way along a winding path, he decided to shorten his journey on the way back and go straight through the forum. There amidst the crowds a talkative fellow shouted at him, 'Aesop, what's with the lamp in the middle of the day?' 'I'm just looking to see if I can find a real man,' said Aesop, as he quickly made his way back home. If that public nuisance had bothered to give this any thought, he would immediately have understood that as far as old Aesop was concerned, he was not a man at all, but only a pest who was bothering someone who had better things to do.
