If we want to get into linguistics...Spoken language and Written language are very different when it comes to grammar. Spoken language tends to be more descriptive, while written language tends to be more prescriptive. Spoken language gets away with a lot of grammatical mistakes because "it sounds right". But proper grammar is proper grammar, regardless if it sounds pleasing or not.

I can't exactly blame you for not know the distinction. First language learners tend to be more descriptive, while second language learners tend to be more prescriptive.
