I bumped into a woman I hadn't seen for nearly three years. The first thing she said to me? "You've lost a lot of weight since the last time I saw you!"
"Well," I said, slightly nonplussed, "the last time you saw me I'd just had a baby."
What I felt like saying was, "I've produced my third child and my sixth novel since I last saw you. Aren't either of those things more important, more interesting, than my size?" But no - my waist looked smaller! Forget the kid and the book: finally, something to celebrate!
