Criticism

"National Grammar Day is a day to set aside everyday English and follow special rules that have nothing to do with how people actually talk or write. On all other days, we split our infinitives and start sentences with and and but. But on National Grammar day, we avoid but altogether and utter no verbs at all. On all other days we use like for as. On National Grammar Day, we like nobody else's grammar all day long. On all other days, we use hopefully as a sentence adverbial. On National Grammar Day, we are no longer sanguine about anyone's ability to speak or write correctly, and we only expect the worst. Or we expect only the worst."
