I have a confession to make. One day after I'd lost a ton of weight (over 100 pounds) and I was feeling all full of myself, I saw a very heavy woman eating a burrito in her car. While I'm too mannerful (is that a word?) to say anything out loud, I did make a disparaging remark in my head. I've never done it again. It made me feel like garbage.
There's some quote somewhere about the oppressed becoming oppressors. And while it was given in a political context, I see it all the time in these forums from so-called success stories. Show me what you look like in five years, then I'll call you a success - and I include myself in that also.
