I'm having that lovely paranoia that all pregnant women get. Enhanced by my natural obsessive-compulsiveness.
There was a lady at the grocery store who occasionally coughed. She had some kids with her. I avoided her area of the store, holding my breath until I was a few aisles away.
I picked up my items, got in line, and then, lo and behold, she gets in line behind me.
I keep my cart between myself and her, and finally explain:
"I'm really sorry, but I'm pregnant, and you're coughing is scaring the crap out of me! I'm just a little paranoid right now, and will be that way probably for another 8 months."
I honestly am not sure if she understood me... she may not have spoken English. But she smiled a little, but seemed a little embarrassed.
I got my groceries to the car, then returned the cart. I was about 20 feet from where I could release the cart, in front of the store, when one of her daughter's came running out. She sneezed w/o covering her mouth.
I shoved the cart hard in the direction it needed to go, turned around w/o watching to see if it made it, held my breath, and ran to my car!
