Oh man .. This is why I can't stand americans.
News flash! The USA is not the only country in the world. This just shows how ignorant you are.
Talking about "Grammar" to improve your own self-esteem and show off superiority. we do self-education , english is one of them. not Including 3 other National languages from our schoolbanks.
It is just sad dictating grammar to a foreigner with your own mother tongue , to be honest.
