Is it there?

Can you see it?
No.
Are you sure this is where you dropped it?
I think so.
You think so?
Well it was wet.
It's all wet!  It's a lake.
Well I'm sure this is the spot.  I remember that wave.
You should have been more careful - it belonged to my mother.
I should have been more careful?  I told you I didn't want to carry it!
Well you shouldn't have taken it from me then.
You didn't give me any choice!
OK, this isn't getting us anywhere.  Let's just keep looking - it must be here somewhere.
