I absolutely hate that construction.
You deserve an explanation, Roger. The reason why I said,
I wonder why Engineer is invariably able to come up with well thought out responses to questions of English and the rest of you seem unable to escape the dismal education you received in English.
is because remarks such as yours don't help people learning English or even those learning about English. You give the impression that negative questions are difficult to understand constructions, constructions that should be avoided.
They aren't of course. They are just another invaluable tool in a speaker's toolbox.
Little children don't have a problem with them.
The thing is, dollars to donuts, this is simply a repetition of something you heard from some wag sometime in your life. If folks like you were to take the time to think things thru, to ask questions, you wouldn't be saddled with all these old canards. And more importantly you wouldn't saddle another generation with these nonsensical ideas.
Lord, we just had a person, who will go unnamed, parading the "don't end a sentence with a preposition" as a real rule of English grammar.
I hope you can see how destructive it is to just keep throwing out all these old falsehoods that were drummed into your head as an impressionable youth. You'll never come to understand the beauty and the complexity of language with this kind of an attitude.
