I was spurred by the fact that having worked for women's magazines myself as a journalist, if you go off and interview a female celebrity, I'd just go in and interview them like I'd interview any human being and talk about the things that interested me. And you'd come back, and you'd file your copy. And then my editor would read through my copy and go, why haven't you asked them if they want kids? And I'd be like, well, I don't know, I interviewed Aerosmith last week. And I didn't ask them that.

But nearly every woman I know has a roughly similar story - in fact, dozens of them: stories about being obsessed with a celebrity, work colleague or someone they vaguely knew for years; living in a parallel world in their head; conjuring up endless plots and scenarios for this thing that never actually happened.

I don't want children anyway,' Caz says. 'So I'm getting nothing out of this whatsoever. I want my entire reproductive system taken out, and replaced with spare lungs, for when I start smoking. I want that option. This is pointless.

For throughout history, you can read the stories of women who - against all the odds - got being a woman right, but ended up being compromised, unhappy, hobbled or ruined, because all around them, society was still wrong. Show a girl a pioneering hero - Sylvia Plath, Dorothy Parker, Frida Kahlo, Cleopatra, Boudicca, Joan of Arc - and you also, more often than not, show a girl a woman who was eventually crushed.

All art is someone trying to tell you something.

I could have written a misery memoir and instead I tried to make it funny. I never complained.

As far as I'm concerned, you're a feminist by default if you're born in the Western world right now.
