I have previously drawn attention to the variety of names by which I am addressed in mail (Prof L N O Louth, Lord Norton O Louth and the like). I had a new one this week. I received a letter addressed to His Excellency Lord Norton of Louth. I thought that was rather sweet. In the same post, I received one addressed to Prof Lo NORT Louth. Imagine my bemusement when I realised both came from the same organisation. Some organisations have me on their databases under different designations, usually Professor P Norton and Lord Norton of Louth, but the scale of the difference on this occasion was rather stark.
