People are often unwilling to answer questions because an answer is a commitment. People are also wary of being led into a trap through being asked a series of linked questions. The famous Greek philosopher, Socrates, did this all the time. He would ask apparently simple questions with fairly obvious answers. The listener would be led, step by step, to an apparently logical conclusion that he would never have agreed to. The natural response to this request might be: '... depends on the question.' '... depends on the context' '... if I am able to answer it.' To which might be added: 'if it is your business'. Parents are willing to help but do not have to agree to subject themselves to interrogations. It is always possible to have a repertoire of stock answers: 'That question cannot be answered without more specific details.' 'The answer to that question depends on the context' 'It all depends on your values and on what you want to achieve.' Being willing to answer a question is still very helpful.
