Well absent - supposing I was upper middle class? We don't have a Peter Jones in Scotland so would Harvey Nicks do instead? 
My Dad shared a bed with his older brother, got a scholarship to 'grammer skool' sold sugar tongs for his first job, joined the army, retired and became, eventually, MD of a large insurance company. What class does that make him? My Mum gathered blackberries and sold them for 1p a basket to help her parents make ends meet, she too shared a bed with her sister, got a scholarship to grammar school, worked her way through the war, married my Dad and hey presto, had me. What class did that make her? We lived in a tiny 2 up 2 down at that time. I was eventually sent to private boarding school, had ballet lessons, joined the Brownies, went riding, grew up in a semi/d house in suburbia and eventually married Mr.G. ?class. My children grew up in a big house with a large garden by the seaside, went to good schools and universities, married university educated husbands and now, bar one, they all live in tiny 2 up 2 down houses, send their children to state schools/nurseries, shop in charity shops and can't afford holidays - so what class are they? I really don't understand class
