LOL, great thread. When I was pregnant I chouldn't engage in conversation where I had to remember lots of names.
i.e.
"You know... umm... that girl? With the red hair? Yes! That's the one, well her cousin, what's her name... umm... you know...? Yes! Well, she's going out with... ummm..." etc, etc.
Actually, who am I kidding - for me that wasn't just a pregnancy thing!
