These people would never be my friends in real life
That's the thing though, I suspect they might be. There is another thread on here about being secretive about mumsnet use. And I do wonder if that's because the persona they portray on here they would be ashamed if people who knew them knew.
They are on here, shouting "yeah, I'd tell the cunt to fuck off and worse, you go girl, you're totally right" when in reality they are rhe polite woman sitting in the corner of your office, or the quiet mum dropping off at school, or the placid mousey looking woman next to you in the supermarket queue.
I genuinely think there is a lot of bullshit on here. Bloke painting your fence, " yes, too right, I'd tell him to fuck right off" In reality I'd bet good money they would make him a cup of tea and say thanks, good job.
I've seen all shades of the social spectrum and very very few people behave as would be portrayed on here. So I do think a pinch of salt is required.
