Sometimes things are not clear. But, you want it. Even if you don't know what it is. Or, you want it but you don't. Most of the times you will say "yes?". It is simply the right thing to say in every situation.

Friend: Blah Blah Blah... So how about it? I'll bring you the money tomorrow.

You: yes?
