Short Story - When one person doesn't want kids

I saw this short story by Hilary Mantel in the Guardian Review on Saturday

It focuses on a couple - the wife wanted children but her husband didn't want a children on their way to a holiday destination. The narrator is the partner who did want children and her reflections on their life together are thoughtful - reflecting some of the thoughts some of my clients come to me with which is why I wanted to share it with blog readers here. The ending was rather disturbing though - it was a metaphor I'm sure.
