Many a worth-while scene is acted out in a space no bigger than that which is occupied by an office boy's stool and hat.

If there is a table in this room, it is often so near it is half out of the picture or perhaps it is against the front line of the triangular ground-plan.

Only the top of the table is seen, and nothing close up to us is pictured below that.

We in the audience are privileged characters.

Generally attending the show in bunches of two or three, we are members of the household on the screen.
