critical mass

I have a friend (well more than one, but you know what I mean). M is a bit of an inspiration. She never misses a workout, she has no food issues and I can't remember ever hearing her say something negative about anyone. I need to be more like M. I'm pretty good about my friends, after all, they are pretty delightful. But. I have lots to say about strangers. You know, "bad blonde", "wearing such and such when people can see her", "can't believe she let her kid get away with that", and other judge-y, not-nice things. Ideally these poor, purloined ladies never know about my snarky comments. I would feel terrible if they did. I feel sort of terrible just sitting here writing this. I know better. I know all about the need to walk a mile in someone else's shoes. So in an effort to practice what I preach, if I can't say something nice, I won't say anything at all. But I'll really try to think of something nice.
