    One evening there had a big dance at the hotel in our town. One of the guest at the dance was a man of

about forty who thought he was very handsome that every girl who saw him would fall in love with him. In

the beginning of one of the dances, he saw a pretty young woman standing besides an older lady at the edge

of the dance-floor. He went up to the girl and asked her to dance. She had seen him to dance before, so she

knew he was good dancer, and she too liked dancing,so she received. After dancing the man asked her, "Do

you tell your mother everything which you do?" She answered sweetly, "She does not mind what I do it. But

my husband always wants to know."
