>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'.
