You all seem to forget that the idea of a single "correct" grammer was invented in the 1600s.Before that, people spoke the way their parents did, because it sounded right. And everyone used double negatives.Really, in terms of grammer, if it makes sense, it's correct. "Dog store to walked I not" is incorrect. It makes no sense. "I didn't walk the dog to the store" is as correct as "I never walked no dog to no store"
