Two of my friends' mothers told them on separate occasions they needed to calm down the food intake and lose some weight. I don't think mothers are meant to do that. I'm sure quite a few do! But it's not really in the job description..
(Mine just talks to me on Facebook chat. She's in the living room. I'm in my room. There are four steps between the two. We're so hip and modern..)
Maybe if she did act as ridiculously as that, I'd listen?
