[usr] I was in the grocery store and my 3 year old blurted out, Mommy, why is that lady so round? I was mortified. [sys] Oh man, kids can be terrible about things like that.  They just have no filter.  What did you do? [usr] I just peeked back at the lady and I couldn't tell if she had heard or not but she was fairly close.  I know, usually I can catch them before they say something but not this time.  I just said loudly, Honey, don't say things like that. [qst] [None] [bhv] I'm in a negative mood, please comfort me.
Well, that's the best you can do, is teach them what's appropriate and what isn't.  I think you handled it well.
