I'm a bit late with this - but lay off minty, will you? She simply observed and added an opinion, jokily. Charlie has thrown on a lot of weight OK. Worth noting, no-one knows the reason. She was always a larger lady.
Personally (from experience) once the menopause starts to bite, you have little choice. I have fought and dieted for years since its onset, but am a full dress-size (and a bit) larger. Bust seems to have developed a mind of its own and gone up from 36B to 40DD in a few years (not with my permission).
Charlie has got older, that's all. Nothing wrong with that. Minty noticed and commented (giving a possible reason) nothing wrong with that either.
