Example:
Person A: If I needed to save $400 a week, what would be the best savings plan?
Person B: That doesn't make sense, how are you able to save $400 a week if no one here makes more than $500 a week?
What can I say to person B to point out that that is not what I'm asking and that they are not answering the question and to just take the question as is in an eloquent manner?
