From A Three Dog Life by Abigail Thomas:

This is my first experience with a dog in heat but the back pain arrived thirty years ago when I bent to pick a canned peach off the kitchen floor and couldn’t straighten up. My second husband seemed familiar with the problem. “My god, what is this called?” I cried as he tried to help. “It’s called my back is killing me,” he said. This version of my back is killing me comes from wearing a pair of stylish new red shoes that pinch my left foot and make me walk lopsided. I don’t know why I keep putting them on except they show off my ankles. At age sixty-three, ankles are my best feature unless you count cake.
