One day a world-famous scientist Einstein met an old (76) friend of him in a street in New York. "Mr. Einstein," (77) said the friend," this seems that you need to have a new (78) overcoat. Look, how worn-out it is! .... It isn’t matter," (79) answered Einstein, "none knows me here in New York." (80) Several years later, they met in New York again. (81) Einstein had become a world-famous physics by then, (82) but he still wore same old overcoat. Once more his friend (83) asked him to buy a new one. "There is not need now," (84) said Einstein, "Everyone here now have known me." (85)
