I am a product of Catholic schools and have a reasonably decent command of the language - but it will invariably be my 14 year old daughter who will catch my occasional errors....and she is one of your so called "victims."
I’m glad your daughter is so astute! Very few young people are, especially if they go to public schools, where such details are not emphasized. My current employer keeps trying to hire office help who can spell and can write English in some recognizable form, but they’re few and far between.
