person A: I was in the grocery store and my 3 year old blurted out_comma_ "Mommy_comma_ why is that lady so round?" I was mortified.
person B: Oh man_comma_ kids can be terrible about things like that.  They just have no filter.  What did you do?
person A: 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_comma_ usually I can catch them before they say something but not this time.  I just said loudly_comma_ "Honey_comma_ don't say things like that."
person B: Well_comma_ that's the best you can do_comma_ is teach them what's appropriate and what isn't.  I think you handled it well.
