Sisters

The matchmaker goes to see Mr Smith, a confirmed bachelor for many years. "Mr Smith, don't leave it too late. I have exactly the one you need. You only have to say the word and you'll meet and get married in no time." Says the matchmaker. "Don't bother," replies Mr Smith,"I've two sisters at home who look after all my needs." "That's all well and good, but all the sisters in the world cannot fill the the role of a wife." Replied the matchmaker. Mr Smith said, " I didn't said that they are my sisters."
