Re: Have you ever written a letter in reply to a letter? (4 Adrian Midgley 1)
Yes, I have.
I did not start writing it under the signature on the original, nor did I cut out lines I wished to address from it and glue them in my reply.
So I'm not quite sure what the relevance of your question is.
I've also sent telegrams and telexes if you want to quiz me some more on archaic irrelevant modes of inter-departmental business communication.
