Why Does Everyone Do It?

It doesn't seem to matter where I go or to whom I speak, it is inevitable that people I am aquainted with or even total strangers somehow throw "Miss Barbara" into our conversation. I don't know how this phenonomen began but it has happened to me and continues to occur. Even a few moments ago when I answered my phone at work, the woman ended the conversation by saying, "Well, Miss Barbara, ..."  Am I the only one who thinks this is very strange?
