I was educated at a public school, and our senior English master, Mr. Bilsborough, would have a cardiac arrest if we had used such words.
Even "Can I open a window Sir?" evoked the response "I don't know, can you?"
The question was then to be re-phrased correctly: "MAY I open the window Sir?"
Double negatives, starting a sentence with 'and', knowing when to say 'who' or 'whom', and correct punctuation were pounded into us. The common usage of the grocer's apostrophe irritates me beyond reason. For instance "Carrot's for sale'.
Today's school leavers can hardly write, let alone put together a sentence using correct grammar and syntax.
It comes from the dumbing down of education and examinations to the level of the least able.
By the way.
Did you know that Clyde Barrow's middle name was 'Chestnut'?
And that he was born In Telico, Ellis County, Texas on Wednesday 24th March 1909?
I'm sure your life will improve for knowing that.
