Answer 1

I am not trying to be mean, even if it sounds that way. I am just trying to point out that everyone makes grammatical mistakes and that not everyone speaks English fluently or as their first language.

Answer 2

@Adeleye If you are addressing someone, the pronoun being used must be separated from the rest of the sentence. "Go to school, boy!" Capitalization also plays a large part in grammar.
