I wrote two today, one for admin purposes and one to a friend. I think businesses don't really know how to deal with letters anymore.. I wrote one months ago to the HM Revenue and customs - I never received a reply, even though one was warranted and needed.. When I called them, they said a letter reply was on it's way.. that was weeks ago.. I wrote a further letter and haven't had a reply.. I really think it's a lost art :P
The other letter was to a friend. She and I used to write mammoth letters to each other. Her's would often take me days to read! This was a relatively short one by comparison :P
