I'm not saying that all pregnant women are annoying. It's just that I've noticed women who are already annoying tend to become orders of magnitude worse when they become pregnant.
For example, someone I know was saying that she invited a pregnant friend of hers to a party, and the friend wrote back, "is the fetus in my belly also invited?" (The appropriate response would be, "No, you must get an abortion if you would like to come to my party.")
I don't know what it is about pregnancy that brings out the annoyingness in certain women. It's like having an extra person inside them makes them feel entitled to be completely obnoxious without any boundaries.
And don't get me started on television pregnancies. I recently finished watching the last season of the Mindy Project (which will be the last season, because apparently, I'm not the only one who grew to hate it with a passion). In this season, Mindy (who is already annoying, but it's okay because her life is so imperfect), becomes pregnant and then suddenly becomes unacceptably annoying. Anytime anyone asks her a question, the answer always somehow involves her being pregnant. She has weird food cravings, bemoans her weight gain, all the stereotypical pregnancy stuff. And she's got a boyfriend who is always saying stupid sentimental stuff about the baby and putting his hand protectively on her belly. *Vomit* At some point, a sassy black woman comes in to make her feel more confident about herself. Just... enough already. Please.
If you are pregnant, you are only allowed to talk about it if somebody specifically asks about it. Or I guess it's okay to mention it if your water broke and you have to leave.
