Even after my "bad" weekend, people are noticing my weight loss, though not in the best of circumstances.

First it was my 18 year old niece who called across a room, in front of a guest "gee your stomach is smaller, it's not as fat as it was."
Then in the middle of a busy shop, when I walked in front of her, my mother at the top of her voice said "You have lost weight, your bum isn't as big as it was". I could feel every eye focusing in on my rear.
I suppose I should be grateful that people are noticing but can't they do it a bit quieter.
