MARTHA--I know; but, after all, your work is yours, not mine. I have been only a helper, a good comrade, too, I hope, but--somehow--outside of it all. Do you remember two years ago when we were camped in Yunnan, among the aboriginal tribes? It was one night there when we were lying out in our sleeping-bags up in the mountains along the Tibetan frontier. I couldn't sleep. Suddenly I felt oh, so tired--utterly alone--out of harmony with you--with the earth under me. I became horribly despondent--like an outcast who suddenly realizes the whole world is alien. And all the wandering about the world, and all the romance and excitement I'd enjoyed in it, appeared an aimless, futile business, chasing around in a circle in an effort to avoid touching reality. Forgive me, Curt. I meant myself, not you, of course. Oh, it was horrible, I tell you, to feel that way. I tried to laugh at myself, to fight it off, but it stayed and grew worse.

MARTHA--[In a gasp of unbearable hurt.] Curt! I don't believe you heard a word I was saying. CURTIS--[Bursting forth as if releasing all the pent-up struggle that has been gathering within him.] No, I can't understand. I cannot, cannot! It seems like treachery to me. MARTHA--Curt! CURTIS--I've depended on you. This is the crucial point--the biggest thing of my life--and you desert me! MARTHA--[Resentment gathering in her eyes.] If you had listened to me--if you had even tried to feel--
