Anybody can write whatever they want and can fabricate everything.
I'm amazed by the number of posters who claim to earn circa 200k (and no not just women). They claim they've 'worked damn hard' to get here and now only need to work about 3 hours a week in some mysterious role. The number of people earning this sort of salary in reality is very low, what are the odds that they're all on Mumsnet?
The number of posters with perfect marriages, still having amazing sex 3 times a day after 65 years of marriage, slept together within 3 seconds of meeting and moved in together the same day, husband covers the bed in rose petals still every day and so on. Again it's not the norm.
Everyone's child is a strapping 6'4 with 'model looks', thin as a rake despite eating 4000 calories a day.
It's just not representative of most people, I'm not saying the above doesn't exist but it's the number of posts on here that stipulate things like this, it feels very exaggerated, does anyone else find this?
