If you considered that sign language incorporates time and place around your body (Past, future etc) and here and there (Left side and right side) or.. even people.
Set up pastor so and so here, set up the next person there in the middle and then the third on the right. point your way through the various interactions while describing a converstation you with with the three of them. So easy.
If you were referring to their kids by name, you refered to them by signs knee high down below the parents. And so it goes with the grand parents above the parents in the middle. You are stacking your way through everything.
I find myself sometimes assigning time, place and who etc to just the left hand while working the more excessively complex signing the right.
IF that does not cause hearing people among us to lock up mentally for a few minutes to absorb
