Yes, it has always bothered me. When you start studying with the JWs that is one of the first things they tell you to distinquish themselves from other religions along with no paid clergy, no donations plates being passed, etc., but as you become involved with the congregation you soon realize that these "titles" are very much there and those with such titles don't want you to forget that they possesd them as they hold a prominent position in the congregation.
I also learned that these "titles" are not to be used outside the congregation. For instance, when a worldly relative of mine died I asked a brother (elder) to give the funeral talk. The newspaper printed in the obituary that "elder" so and so would be giving the funeral service. When the brother heard about his title actually being printed in the newpapers there was hell to pay. I was approached and questioned by two "elders" as to how this came about. I being new in the truth did not realize that I should not have said "elder" so and so to the undertaker who was preparing the info for the local newspapers. Well, is that not what he was, as I was so often reminded when I studied with him and his wife? He was constantly referring to himself as "an elder" and his wife as one of "the pioneers".
Also, don't forget about the other title that I don't believe anybody has mentioned yet..."elder's wife".
