I am a nurse, definitely from a working class background for which I am proud. I had it said to me that it's the poor or thick girls that become nurses. To be fair the person who said it did not know that I am a nurse but still...Is that what people think? That you don't need to be clever to be a nurse! I studied for three years, I also have post graduate qualifications too. My job is demanding and requires a lot of time and attention. I am not thick! Apparently bright girls being teachers...
