Doesn't pay to care sometimes

I had a heated argument with a friend after calling her out yet again about her constant complaints about her weight. You know, "I'm fat, my fat stomach…" my fat this, my fat that, and she's always cleansing. I told her I 'm tired of hearing it and why don't she stop eating altogether, to stop belittling herself because from where I'm standing that's what is sounds like. I help her out at the salon on Saturdays and so there was an audience and of course everyone had an opinion…in my favor thankfully, but she just couldn't hear what I was saying. She gets confrontational and thinks I can't relate because I've never had weight and I shouldn't tell her what not to do, blah, blah, blah. I finally told her that if she doesn't like the way she looks, then do something about it. Then I went deaf.
