You sound like my brother when he starts ‘instructing’ why you need to listen to him.
I usually leave alone the grammar failures on this forum. However, these persons were going back and forth on this issue, and I know the truth of it.
If I sounded that way - which I assume is a negative thing in your view - it is because, if I simply post a succinct reply, I am typically subjected to snarky derision in return.
I am tired of the incivility by many on this board. I was therefore establishing my bona fides before the fact, instead of after, in hope of forestalling such abuse.
