fpherj48- I am in agreement with almost everything you wrote, but unless I am mistaken (and I could be I suppose) in an email or on the internet, using ALL CAPS is like screaming or shouting at someone. Why are you shouting at us?
To answer the original question, like a lot of you, whether I correct someone depends on how well I know them, whether I can do it privately or quietly, and whether I think they are the kind of person who wants to improve and will appreciate the correction.
Personally, I always want to be corrected, because that is how my speech and vocabulary improve. I make sure my friends and acquaintances know that and I make sure I both laugh at, and learn from, my mistakes.
