In the past few days, I have received correspondence addressed to:
Professor Lord Norton of L
N. O. F. Louth
Mr Norton O. Louth
I know software has enabled mass mailings, but some organisations do seem to have problems coping with anything out of the ordinary.
At least I know who I am. I think.
UPDATE: I caught the train last night to London. My ticket has my name as PROF L LOUTH.
