My father-in-law has five daughters. No kidding. And all he ever wanted was one son. He tried the first time – no luck. A daughter. He considered giving up, but his wife convinced him to try again. And so he did. Nope. Daughter again. He thought about quiting, but his wife convinced him to try one more time. Who knows? He tried. Daughter. Again.
He took a break for a few years to think things over. And he thought hard. As a result, he divorced his wife. And married another woman. Who already had a son from previous marriage.
Tricking the nature he tried again. And he got it back hard. His wife gave birth to twins. Two girls that is.
Five daughters later, I don’t think he will try again.
