I too congratulate you on your English.
One thing I would like to explain, the English public schools (a misleading description, not only are they private schools, they are the most exclusive private schools,) all run a system of houses, so called because although there are day pupils (as I was having won a scholarship) most pupils were boarders and the were accommodated in actual houses, with a house master and his wife acting in loco parentis. These houses compete in physical and intellectual activities and adolescent boys being what they are, the rivalries are exaggerated wildly. (I’d rather be eaten alive by rats than be an Oldham’s man.) It’s just silliness.
The school was founded in about 1550 by Royal Charter granted by King Edward VI. None of the original buildings remained but we all believed some of the original masters did!
BTW they’re called public schools because at the time mine, and the even older Eton College were founded there were guild schools which accepted only the children of trade guild members, church schools for boys destined for the clergy, and public schools to which any member of the public could send their sons so long as they could afford the fees.
