There must be a better song to sing

On our first day at college we were watching a film from early eighties, Educating Rita with Michael Caine (he was brilliant). Must say, I really liked it, it reminded me of other film,My Fair Lady at some point, where a professor is trying to turn a raw stone into the diamond. The main thing I liked about the film, was, that no matter how old or where one comes from, if one has a willingness to achieve something and change life, it is possible. They say that if you know what you want then it is a half of the success already.
In one of the scenes where everyone is in the pub singing some song, Rita's mother says "there must be a better song to sing", think that symbolised that she was sorry for herself and her life. At the beginning of the film Rita is just someone from lower class I would say, very straight in her opinion, seems everything is wether black or white, if we assume that we come from our childhood then it is pretty clear that this girl did not have enaugh attention from her parients.
I think this film was chosen by Dieca to show us what we should come out as :)
I decided to come to college and change life, was working in office before and after some time I understood that I don't want to do something I am not interested, but find some sphere which I can feel comfortable and which can take me to another level.
