Sorry, I feel ashamed of myself but being a non native speaker it is difficult for me to do it perfectly. I am confused about proper nouns as well and you guys think that I deliberatly don't capitalise them but sorry for that. It is easy for you because you are native speaker and you guys must be wondering that it is a very tiny thing to understand but for a non native speaker sometimes it becomes very confusing. It must be very frantic for you because its not a big thing but I am confused so I want to appologise. Sorry guys.
