One day the famous American scientist Albert Einstein met an old friend of his on a street in New York. “Mr Einstein,” said the friend, “ you need to put on a new overcoat. ” “It doesn't matter,” answered Albert Einstein. “No one knows me here in New York.”
Several years later, they met in New York again. Einstein had been a world-famous physicist after then but he still wore the same old overcoat. Once more his friend persuaded him to buy a new one. “There is no need now,” said Einstein, “I have lived here for a long time.Everybody here has known me.”
