Ha ha! I stand corrected. I know I don't want to play any grammar games with you. I suspect it would be no contest for you. It's just that I hear so many grammatical transgressions from people who have not only completed high school but have college educations, that I'm somewhat aghast. So where does that leave me...at?
I guess the lesson I learned in my Modern English Grammar class taken decades ago is still germane. There is standard English grammar and many other English grammars. The point is to make yourself understood.
