Little Ironies- Male Child

They were starting to hear something, it started soft, then it became louder and louder! To such an ear-deafening extent. Worst still, the operating surgeon emerged from the operating theatre with the new-born child, making the cries of the baby even louder. Shouting through the cries, he said," Congratulations! It is a male child! I heard that your family has been longing for one for years!"
With that, he left the baby in the grandmother's arms and went back into the theatre to attend to the mother.
The proud grandmother of 8 asked,"Chuan Poon, I see that you would have to give up your idea of changing your wife, eh?" Chuan Poon's cheeks turned red.
Just then, Chuan Poon's phone rang. He fished it out of his pocket. He stare hard at the little screen of the phone. It was his mistress. What was he to tell her? He rejected the call, unable to think of an explanation. He was so deep in his thoughts that he did not realise that his wife had been wheeled out of the operating theatre, into a ward, and that his mother-in-law had followed.
Half an hour later, he was still deep in his thoughts, until his mistress came up to him and splashed icy cold water onto his face," So, tell me! What is the end result? Is it a boy, or a girl? Why were you so dazed?"
His eyes turned watery, and he replied," Dear, I am sorry, the kid's a boy."
