Guess I'm just stuck in the old fashioned upbringing I had. I still call people MR. MRS. or Sir. If these people become close friends by all means we do call each other by our first names but otherwise I would become tongue tied calling people older than myself by their first names. And I also don't like being called dearie, honey or sweetheart by clerks or other stranfers. It just makes me squirm. Guess we all have our preferences, just the way I was raised I guess. A bit straight laced maybe but I raised my kids the same way. I've known some colleages for ages and we are close but I still refer to them as Mr. or Mrs. because they are older and more experienced than I am .
