Make it the client's idea!

If you practice your command of questions well enough, you will soon find ways to discover actual clients' needs, and though you are not going to come up with your brightest solution right away you may probably turn their attention to things that they could possibly envisage to approach the issue worrying them. Tactfully helping them to weigh over the pros and cons of each of these issues, you will soon find out that clients respond to your helpful questioning by finding out a way out for themselves. It is most likely to be the response you had been longing to propose. Your silence may be widely rewarded by your listening skills.
