That comment on my report was written nearly 50 years ago and, as we know, such a lot has changed in that time.

Standards were strict then, and the written word was to be in standard English, although even then it would differ from the spoken word. I would say it still is different, and should be so.

I would also say it is useful to know the difference, but only if individuals think so. Many get by just fine with everyday speech. I'm not so sure that is adequate where, as an example, business communications are concerned. A few years ago, I queried a procedure with a young, very sweet young lady at the bank which held the business account for our house [[divided into flats). When I opened the letter sent in response, her opening line began "Not to worry...." and continued in similar vein.

I think what we are discussing here is the blurring of the line between formal and informal communications - ?
