ADAM. Ugh! [_He shudders and sits down on the rock_].

EVE [_throwing herself on the ground beside him, and grasping his knee_]
You must be careful. Promise me you will be careful.

ADAM. What is the good of being careful? We have to live here for ever.
Think of what for ever means! Sooner or later I shall trip and fall. It
may be tomorrow; it may be after as many days as there are leaves in
the garden and grains of sand by the river. No matter: some day I shall
forget and stumble.

EVE. I too.

ADAM [_horrified_] Oh no, no. I should be alone. Alone for ever. You
must never put yourself in danger of stumbling. You must not move about.
You must sit still. I will take care of you and bring you what you want.

EVE [_turning away from him with a shrug, and hugging her ankles_] I
should soon get tired of that. Besides, if it happened to you, _I_
should be alone. I could not sit still then. And at last it would happen
to me too.

ADAM. And then?

EVE. Then we should be no more. There would be only the things on all
fours, and the birds, and the snakes.

ADAM. That must not be.

EVE. Yes: that must not be. But it might be.
