My apologies as I ,too, earned a BA in English.
I read books like “Eats Shoots and Leaves” and cannot supress the urge to poke when I see such examples. My mother made sure that I knew correct usages, but always took the time to highlight incorrect or poor linguistics as if to say, “There it is...Don’t step in it!”.
Be aware, however, that I am also teaching my children correctly so that when the grading competition begins, the winner will be clear.
One can raise literate children but not by relying on the schools
