>The reason I commented on 'whether' is that it is not really a question to me, rather a conjunctive as in ' I wonder whether you can get away with that'
Don't know whether you had a chance to exchange messages with people who put a question mark on end of such a sentence. Their reasoning is that the sentence
contains a question, so it should have a question mark. Which is silly, IMO, because there is no reason for a question mark on a sentence, unless the sentence IS a question. So, our exchange usually looks like this:
I don't know should I stay or should I go?
Yes, you don't know.
