I hear you. I'm usually like that too, but this is a rule that I dislike so much that I'd rather not follow it. I consider English without that rule to be an improvement of English with that rule.I'm a perfectionist. To me, rules are rules, and I will follow them to the best of my ability. Note that I usually won't obnoxiously correct someone unless I'm deliberately trying to irritate a family member or a close friend. It is just a fairly minor annoyance.
