One Sunday morning Charles burst into living room and said, "Dad,Mom, I have some great news for you,that I am getting married to the most beautiful girl in town.She lives a block away and her name is Agnes." After dinner Charles' dad took him aside and said, "Son,look at your mother, we got married for the past 30 years. She is wonderful but she has never offered much excitement in the bedroom, so I used to fool around with a lot of women. Agnes is actually your half sister and I am afraid you cannot marry her." Charles was heartbroken. After eight months he eventually started dating girls again,and a year later he came home and proudly announced, "Diana said yes! and we are getting married in June. Again his dad insisted for another private conversation and broke the sad news that Diana was also her half sister. Charles was livid, and finally decided to break the news he has shared with his father to her mom. "Dad has done so much harm, I guess I am never going to get married'' he complained." Every time I fall in love, dad tells me "the girl is your half sister." "Hee hee" his mom chuckled,shaking her head,"don't pay attention to what he says. He is not really your father."
