"mrs." ritta

I sent a work email today, and the response came to Mrs. Ritta. That annoyed me. Why would you just assume I’m a Mrs.? This was a conservative Christian company, so I understand their reluctance to use the “feministic” Ms. But couldn’t you go the more informal route and address me by my first name? That is how I signed the email, after all! I wonder if I’d have the same reaction if I was married and someone called me Miss . . . I kind of doubt it.
