My brother has never set foot in a state school, having been educated at a Prep school and then a well-known public school.
I have been edcuated in the state system. Despite my awful primary education (universities back in the 1990s were a great leveler) I managed to achieve an MSc from a top redbrick university, but that's because I worked my socks off at university to catch up and to fill in the gaps thanks to my p*ss poor school education.
My brother is like a stranger. He calls me names - pleb being a favourite. He never invites me to his family's gathering unless he has to and he has admitted to being ashamed of me. For example, the last family gathering I attended was my nephew's baptism in 2006 - my father refused to attend unless my brother invited me and my family along as well. It was very painful to hear that my brother had told so many people that he was an only child. There were a few awkward silences as I result. At one meal, having spoken about my career and university degree, another guest asked, "so you went to x College as well?" I replied no, and that I attended a secondary state school. When she asked why, I replied, "because I'm female" and laughed it off. What else was I suppose to say?
I have always been envious of my brother's public school education. For example, I would have loved to play more hockey. I played for my county junior team but quit at 16 because it was a 2 hour drive to get to training. My brother, who never made use of his school's fantastic sporting facilities, only needed to undertake a 10 minute walk. This was true for swimming as well, and cross country running, but by the time I was 16, I just abandonned all sports. I was also miserable at my state school because no one else shared my interests, and my family were considered "odd".
I haven't seen my brother since 2006 and I doubt I will ever see him again although I am assuming that he will attend my parents' funeral in the future.
