@WBYeats,
Quote:A friend of mine has just asked me a question (,) which question is very awkward(,)and which I do not want to answer. What tense is correct/wrong?:
I hope this is the only time you asked/have asked such a question.
These two don't address the scenario you have described, WB. They could be used by the respondent if they held the dismissive meaning inherent in,
I hope this is the only time you ever asked/have ever asked such a dumb/stupid question.
The present perfect aspect would be the more likely of the two.
??I hope this is the only time you are asking such a question.
I can't envision a situation where this would work atall.
