I would draw but the woman sits on the other side of the coffee table and would not be able to see it. I think it would help her understand what I am saying. And I am not an artist at all - I would probably use X and Y and maybe blackacre and greenacre (nothing like CE's artistic renderings) - I would use it so the woman could follow what I am saying. Also it might help me think. But I also like writing - although probably not at an appointment - because I can think about how to best express something.
The second one I see suggested drawing - but I did not see that it would help me with that one as communication is not so challenging with the second one.
