Your grammar seems correct . But ! I'm puzzled , how can your grammar .... up your reading . I would think there is a possibility it's your reading comprehension . Seems to be a BIG PROBLEM on THE INTERNET . Though you think everyone should have the same level of Education and Skills as the USA , WE DON'T !!! Yours is one of the lowest in the world .
And on this fabulous medium , you can find examples of how bad your Education levels are on EVERY SITE you can peruse . AND SNOTTY ATTITUDES PREDOMINATE MOST SITES PERIOD ... SEEMS EVERYBODY THINKS THEY'RE RIGHT .
You're out of control, man.
If you give your posts a serious look, and still think the issue is bad reading skills of the counterpart, you have a serious issue.
