Reminds me of when my out of state daughter & family came to visit, I hadn't seen her in almost a year. The first thing I asked her was, "are you pregnant again"? Answer, No dad, I'm just fat"! Than it got worse.
I learned a lesson. Never, never ask a woman if she's pregnant, even if she looks like she's ready to drop a kid any minute now.
I go up to skinny women and ask "So, when's the baby due?"
