Sometimes I think class is something people are largely born with.
I know of one woman who had a very working class parents, extended family etc, lived in a poor area, education was very poor. Family have strong regional accents, and could be said to be uncouth. Swearing, farting, burping was hilarious etc. Reading was for twerps and "poshies".
However this woman is totally unlike that. She is a gentle, quiet soul who loves reading, (she doesn't just read all the classics, she really knows and gets them in a way that can't be learned from textbooks). She did go to university, the first in her family and without the support of her family (again, uni is for work-shy "poshies" and got no help at all financially or otherwise, consequently, she worked 3 jobs to pay her way (prior to having to pay fees though luckily). She is humble and dreamy, she has lovely natural manners and finesse, all unlike her family. She just doesn't seem to have come from that tough environment yet she very much did. And it's not as though she has consciously rejected it - on the contrary, she is proud of her family and isn't embarassed or ashamed of her background in the slightest, but if ever anyone was middle class it's her whereas her background is very "Shameless" kind of working class. Even as a child she was like this and stood out quite a lot at the tough local primary (needless to say she was picked on).
How can anyone explain that?
Conversely I know people who were born into firm and long-standing middle class going back generations, who behave like "rich chavs" and have always tended to behave more "working class".
I don't get that either!
