Oh gosh, I have a friend who fits this description to a tee!
She is very posh in my opinion - privately educated, parents live in a huge house ‘with land’ somewhere in Aberdeenshire, ponies, ski holidays every year etc. Her husband works in finance and she was a lawyer but stopped working when she had her son.
They live in a big, rambling Victorian villa. It’s not dirty but it’s always chaos - piles of wellies in the front porch, books stacked higgledy piggledy on the ottoman, newspaper kicking about on the sofa, dogs everywhere. The house is full of lovely, interesting things and if you ask where she got them it’s always something vague like ‘daddy’s family used to import silk rugs from Asia and this one had been knocking about in an attic for years’. She has proper art on the walls, every room has bookcases, big fireplaces with roaring fires in winter etc.
She has a 4yo son who is lovely and very polite, always bending your ear about something he has just leaned or his latest interest. Last time I was there he was showing me his collection of birds nests and egg shells and wearing a pink fair isle jumper he had apparently inherited from an older cousin. He has mad ginger corkscrew curls which are lovely and actually very well kept, so if nothing else she must be managing a curly hair routine!
She even has the pine table in the kitchen, and the aga with the whistling le creuset kettle 😂 all her pans are le creuset too but ancient and well used.
Shes actually lovely, truthfully - no airs and graces, and she’s the kind of person who always has time for a chat, very kind and empathetic. She doesn’t stand on ceremony at all and I definitely think there’s a kind of casual confidence that comes from growing up monied and knowing that everything you have is quality. Last time I saw her she was giving a bath to an egg-bound chicken in the kitchen sink and didn’t give two hoots (clucks?) about how messy it was in there (I had popped by without warning because I was dropping something off and she seemed delighted to see me, no embarrassment about the breakfast things still being on the table late morning and straw from the chicken coop on the floor).
