Sarcastic reader's letter (1999)

I was rooting through files and found this 1999 letter, which as I recall related to me calling mains live as,  erm, 'live'  rather than 'Line' which the reader claimed was the correct term I should use.  I had pointed out that Line means something quite different to an audio or PA engineer, and most ordinary people understand mains live as 'live' too.

In my experience, I always found the rudest and most intolerant letters came from retired engineers with too much time on their hands. Anyway his reply amused me, so here it is.
