My husband, Harold, called me a fat pig right before our guests arrived for dinner. I stayed silent, but what I set in motion that night left him shocked in a way he never could have imagined. I am Margaret Foster, and this is my story.

The day had been long and full of careful work. I’d woken up at dawn to start the rosemary chicken, just the way Harold liked it. Our kitchen in our quiet Manchester, New Hampshire, home smelled of garlic and fresh thyme. I pressed the white linen tablecloth until it was crisp, set out the good china, and polished the silverware until it gleamed. Everything had to be perfect. Harold’s colleagues from the firm, Mr. and Mrs. Henderson and Mr. and Mrs. Davis, were important people, and I wanted my husband to feel proud of his home.
