I too, am a grammar nazi. And I will tell you, I learned that I am not liked as one, no matter how right I am. And I finally came to peace about not pointing out every error, LOL. I tended to hide online behind my grammar nazi comments to complete strangers; or I was correcting fb posts, back in the day. I am guessing if you are calling out spelling mistakes in work emails, people are quite annoyed. Just a thought, based on personal experience - I’ve seen lots of dislike of grammar correctors. I couldn’t understand why, but there it was.
