Time for my list of things to never ever say to a pregnant woman unless you want her to rip your eyebrows out and feed them to you hair by hair...
1.) "You're glowing"
No, fuckhead, that is called sweat. It is merely reflecting the light off of your shiny bald head.
2.) "Wow, you've really popped"
Wow, you've really gotten fat and ugly and wrinkly. Oh, wait, I can't comment on you but you can feel free to comment on a pregnant woman? So sorry...
3.) "You sure you're not having twins?"
You sure YOU'RE not having twins?
4.) "So, you decided to try for that boy, huh?"
(This one really gets to me, especially given my history.) No, we were actually hoping for a hermaphrodite with a puppy's head.
5.) "I only gained three pounds when I was pregnant!"
Bugger for you. My goal here is to have a LIVING child, so really, my weight gain is the last thing that I will obsess over because I kinda have bigger fish to fry, mkay?
