My sister is posh but I am not. She has a four bed house with a sitting room & dining room in a leafy modern private estate, plays golf, goes to dance class, is very involved with the History group and does lots of charitable work. She is tall and slim, spends lots of time and money at the hairdressers, has a brand new car every 2 years, a huge pension(She was a senior civil servant), shops at Sainsburys, has a gardener and lunches with friends a couple of times a week.
I have an ancient 2 bed cottage, we eat in the kitchen or on trays in front of the huge TV in the living room, shop at Aldi, I tend our huge garden growing masses of fruit and veg, making jam etc. I am short and dumpy, buy clothes in Charity shops and make do and mend, our car is a 5 year old Berlingo. Having worked mainly in the voluntary sector I have no works pension. Neither has DH who was self employed. I am a political activist. I get my hair cut at the barbers when I accompany DH there.
The thing is Big Sister was always POSH. My friends at school used to remark how posh she was compared to me. she even sounded posh, while I had the local accent. BS was a prefect in an immaculate school uniform with braid. I was a year behind at school so I got the blazer with the braid unpicked. Teachers, Grandparents and My Mum were always saying - 'why can't you be more like your sister?
I love my BS dearly and would not change a thing about her, though I wish she would stop telling me what I should do to improve myself. Nor do I envy her, I would rather be me. All I am trying to say is that it is not wealth or possessions or life style that makes you posh or not. Some people just are POSH and others, like me, are Common.
