I tried very hard to teach my kids to be sensitive, but it was a challenge.  When my little one was about three, I was stopped in a store by a friend for a few words.  The lovely lady was quite portly.  I knew my little one was dying to remark upon the unfortunate lady’s girth, so I shushed her and hurried to get away before her mouth went off.  As soon as we turned to walk away, she announced, “I sure was nice not to call her a big, old fat lady, wasn’t I?”
