You are right Marisa "Passed down to us in our folklore" Sometimes I wonder if its a question of pride. There is an old saying 'Pride comes before a fall.' I remember a teacher at school talking about the subject of pride many years ago. She suggested aspects of pride are positive. Pride in your children, your parents, the qualities of your partner etc, but if you feel the need to express regularly the pride of where you come from there might be an element of doubt in your mind, she offered.
When I return to the UK in August this is something I will take with me and it is evident in "the first person plural" if that is the right expression. (Someone will correct me if it isn't). Our this and Our that. I hear it every day in the press, all media and everyday conversation. Our highest mountain, our deepest lake, our barrier reef and our boys who just thrashed the poms at cricket. I wonder if there is anyone in the UK who refers to London as "Our nations capital?"
So it goes on, a film trailer on TV announced in that deep gravelly voice, "Starring Brad Pitt, George Clooney and "Australia's" Cate Blanchett. Why is there a need to do that???
But the best one I ever heard was "Our stars are better and brighter than those in the northern hemisphere." OUR STARS !!
