So I had my first go at using my title today. A telemarketer called. "Hello Ms Hartnup, how are you today?" I corrected her. "Its Capt Harntup, actually" She responded with, "Oh, sorry, well done. Where have you served?" My response, "Adelaide, Sydney and Brisbane this week." "Oh, ok, it must be hard on the body." "Incredibly!" I replied. Yeah, maybe I might be better off sticking with my unofficial title from here on in.
