Maybe she didn't want to put the idea into your head? You know how if someone says "Are you having so and so yet?" it sorts of starts it off?
I wish my mum was here so that I could tell her that I now, finally, understand. My one abiding memory is of her moaning about her lack of waist and the fact that she had put on a stone and nothing looked right and me thinking "For goodness sake - you're fifty-three - who's going to be looking at you!" Fifty three seemed so old back then!
