The Underbelly of Being Pregers-Just Leave Me the Crap Alone!

There are many things I don't like about being pregnant, but by far my least favorite thing is how the pregnancy seems to put a big sign over my head that reads,
"Hey I'm Pregnant--TALK TO ME!"
Anytime I go out I am accosted by perfect strangers wondering things about me that are, frankly, none of their business: when I'm due, the sex of the baby, what names we're thinking about. I wish I had the nerve to stick it to these people and say in a very offended voice that I'm not pregnant, but I always chicken out. I've even had some women come over and rub my belly in the middle of Target! But the worst was when I was pregnant with Cecilia and a man came over, thumped me on the tummy and said, "Yep! Sounds ripe to me!"
Once, when I was pregnant with Gareth, a woman walked over to our table at Fuddrucker's and asked when I was due. On this particular night Cecilia had been a beast! She didn't feel great and had spent much of the meal acting out and crying. Josh finally had to take her out to the car to discipline her. It was his exit that prompted this woman's advance. "When are you due?" She asked. I had seen her paying attention to us while we were eating and knew she was coming over to chat. I took an inward sigh, plastered a polite smile on my face and replied, "The end of the September." Her eyes widen and she said, "Oh well, that little one you have now is in for a RUDE awakening when that baby comes." And then she stood there and waited for me to respond to her idiotic comment. I looked at her like she had lost her senses, scoffed and left the restaurant. I've never been angrier driving home from dinner.
But the most obnoxious of these offenders are the women (mostly at checkout counters) who ask when I'm due and then after my response let their eyes get big and round and say, "WOW! Are you having twins." or "4 more weeks! You look ready to explode!" This happens at least 3 times a week.
How can people think this is appropriate or helpful. Do they think they are making me feel better about myself? Do they think that it is easy to keep the crazy under control when you are this huge, this pregnant, and this hormonal. Sigh. I just want people to leave me alone or ask me other questions about myself. I am more than just a baby warmer/grower, right? There is a human being under all this water and weight? Maybe? Just leave us pregers alone. Odds are we don't want to talk to you!
