"Actually, I'm not pregnant. "
"Oh. But you look so...SKINNY! "
Don't you hate the taste of your foot in your mouth? I know that taste all too well.
Lesson for us all: NEVER, EVER ask a woman if she's pregnant. EVER. I mean EVER. I thank heaven that I was only eavesdropping, and that I was not the party asking, or the party that got asked.
