Oh yes, my mother does it in a very demeaning way. I know she does not mean to do so. But the fact remains that she's being critical of the person she is looking at. She puts too much importance on people's appearance, and is not tactful when she thinks someone is poorly dressed, overweight, or "could do better". The fact that she'll be 80, and has poor hearing exacerbates the problem. She will say things she shouldn't say, and does not realize the people she is talking about CAN hear her.
A few of my sister's are quite overweight, and it seems to be my mother's favorite topic some days. I know she talks about me to my other sisters the same way she talks about them to me. It's actually become a family joke. Unfortunately, for my heavy sisters, it's painful. Ah, the joys of coming from a big family! The bigger the family, the more disfunction there is to go around!
