>>>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.
>
>Or 'yes, you should stay or you should go'.

But that was not the question. The question is always with the verb, is it not? And the verb in that sentence is know.
