This suit is so dirty that it will stand up itself. Mr. Field: All right, I'll take it to the cleaner's. But you see, I 'm always so busy. It takes me so much time. And I have so much work to do. Mrs. Field: I can't understand why you always buy dark suits. Why don't you buy a few light - colored suits for a change? Light - colored suits are much nicer. They will make you look younger, too. Mr. Field: Perhaps they will. But they easily get dirty in London. London's air isn't exactly clean and light - colored suits will show the dirt. I'll have to take them to be cleaned once a month. Mrs. Field: That's better than once a year. Dark suits get dirty just as light - colored ones but they don't show it. At least, you can buy different color suits for a change. Mr. Field: That is why I wear them to look attractive when I go to the theater or to a party. Everyone wants to look attractive before others. Mrs. Field: That's right! You at last got the message. What does the man agree to do with the suit?
