Besides, if you want to be specific, calling Parker out on the improper usage of the verb form of 'conversation' is actually more specific than just grammar. It's a conjugation and vocabulary issue. When I think of grammatical corrections I think more about the mechanics (commas, apostrophes, etc). Technically grammar implies diction
and syntax, but I think that colloquially and connotatively speaking it generally applies to mechanics.
God help you all if I start nitpicking all of
those mistakes.
