Rachel doesn't want kids, you see, and so she finds it boring when other people try to tell her about theirs.
Rachel thinks that people should be more sensitive to her feelings, and not engage her in conversation about things she finds boring.
Rachel would prefer it if you could talk to her about "books, or Michelle Obama, or Mad Men".
OK Rachel, I will talk to you about Mad Men. Mad Men is a television programme that portrays (among other things) misogyny and sexism in 1960s New York. In Mad Men, men lark about drinking whisky and copping off with their secretaries, while mothers are confined to the home, where they are neither seen nor heard.
I can see why this programme has struck a chord with you, Rachel, because you also seem to be quite keen on the idea that mothers should be confined to the home and neither seen nor heard.
According to you, not only should mothers not talk to you about their kids (which is fair enough), but they shouldn't talk to each other about their kids, either:
The other morning, while I was thinking about writing this piece, I logged on to one of the dozens of websites now devoted to all things baby-related. The discussion subject of the day - email us! - was the funny ways kids mispronounce words. Really. To which I say: new mothers, by all means, tell your own parents, or a close friend, about how your son said the word "bottle" and made it sound like "bottom". But don't be incontinent. Don't tell the entire world. Telling the entire world will make people, and not without reason, think that you have lost your mind.
Mothers: know your place. No matter how lonely or bored you get at home, do not seek out the company of other mothers on the internet. Do not ever discuss your baby's foibles, not even in an internet forum designed exclusively for mothers. Do not make friends with other mothers on the internet, not even if you don't know any other mothers in your real life. Not even if your own mother is no longer there to talk to about baby things. Not even if you use a pseudonym to hide your terrible shame.
Because Rachel Cooke might log on to Mumsnet and read what you say. And Rachel Cooke might find it boring, because Rachel Cooke doesn't want a baby.
But you don't hear her telling the entire world about it.
