那位GGMM帮我写一段有意义的英语对话啊!

A middle-aged couple,with two beautiful daughters,decided to try one last time for the son they always wanted.
Soon,the wife became pregnant,and,nine months later,delivered a baby boy.The joyful father rushed to the nursery to see his new son,but was horrified to find an incredibly-ugly baby.
He went to his wife and said,"I cannot possibly be the father of that hideous (丑恶的） child.Look at the two beautiful daughters I fathered."
When his wife blushed（脸红）,he became suspicious,and demanded,"Have you been fooling around on me?"
His wife confessed,"Not this time."
