You haven't, as you know.
I am late to this post and have now read through more than enough. You've been answering the OP's actual question honestly and from your perspective, and a bunch of random weirdos are bending over backward to find reasons to argue. Thank you for your patience with them - I love it when I can add more chuds to my block list without having to go through the hassle of engaging with them myself!
Were you better or worse at proofreading when you were 9?
