Training People Takes Time
When someone finally gets around to that question, “What do you think I should do? The ball is in your court.
You can, of course, ignore the question and not respond. But the person wouldn’t have asked unless he or she was serious about wanting your input. Your failure to respond, or at least to listen, tends to endorse what he or she intends to do. Since you didn’t respond otherwise, the person assumes that you are in agreement. It’s dangerous.
Failing to follow through when you are asked for help may actually result in doing more to harm a person than to help. If you do not have the time to help someone, or you feel the better part of discretion would be to let someone else help (which may be appropriate when the one who needs help is close to you), or you simply are not qualified, you still must do something to get the ball across the court.
