"I told Carl, the boss, that I hadn't decided about kids yet, but I absolutely would never quit my job to stay home with kids. NEVER. He nodded politely and hired a single man. "
I can absolutely understand why Carl did this. The fact that you even wanted kids was a red flag. I've known so many Moomies who go on and on about their "dedication" and how they are so excited to get a job, yet shortly after sprogging it all goes down the tubes. Hell, even when they get knocked up with a normal pregnancy, they refuse to travel and start demanding all kinds of special treatment when it's not warranted.
That doesn't mean it's always a good idea for women to announce they aren't having kids at all. Some of the CF posters here and elsewhere have had negative experiences with this. One got the whole, "you're un-nach-rul because you don't want to have pwecious baybees" routine. Alternatively, you could get the job, but be working all the crap hours because "people with famblies need time off," and you still get passed over for promotion because "you don't need the money as bad as Fred the Family Man because he has keedz to feed."
Some days I think having a uterus = you're fucked.
