I want to answer the question but I don't intend to do so.
I don't understand, why are you not going to answer the question?
Are you trying to trick me?
I'm just trying to understand the details of the situation, but I can understand how demanding it might be for you to answer some questions. I have declined to answer a few questions in the past, myself. But if you owe someone an answer or an explanation, then you definitely need to answer as they may be depending on the answer from you. See if you can get an idea of how important it is for you to answer, and decide if it is necessary or not.
What do you mean? Of course I can't answer a question that I don't intend to.
I suppose it is your right to decline to answer a question, but you may be causing other people a lot of problems if you refuse. They may require an answer to an important issue, or they might need your response in order to help you out with something. You need to figure out how important this is before deciding whether or not to answer.
