Never...Never...
Here's the scene at Kroger the other day:
strange man: "how much longer do you have?"
Steph: "8 weeks"
strange man: "do you think you're going to make it?"
Steph: "that's my goal"
strange man: "Is it twins?"
Steph: "uh, no, it's just one."
strange man: "Isn't the female body amazing. I mean how do women carry all that weight. It just doesn't seem possible."
Steph: (silent blank stare while the voices in my head are saying "beep, beep, beep" as the man is trying to back-pedal out of this hole he's dug)
strange man: My wife is pregnant and I just look at her in awe that she can walk around for 2 people.
Steph: why don't you go buy her flowers (pointing to the floral department)
strange man walks away.
Never ask a pregnant woman if she's having twins. She will tell you if she wants you to know.
