He swayed suddenly and realized that he was at the end of his endurance, and now would in all probability make a complete fool of himself. He would commit the unforgivable folly of issuing a challenge that he couldn't back up.
He shook his head violently, trying to clear it, but his dizziness increased. The landscape about him began to pinwheel and he saw the streets of the colony through a wavering yellow mist. The store fronts danced, the rusting and discarded machinery on a side street began to move and come to life, to clatter and waltz about.
A woman moving toward him seemed to grow in height, her oxygen mask widening out, overspreading her face. For a moment she seemed like an impossible ballet figure in a danse macabre, pivoting about on her toes as a caterpillar tractor came rushing toward her through the thin air of Mars.
Then two colonists were supporting him, holding him tightly by the elbows, refusing to let him collapse. It was outrageous, because he wanted to collapse. He wanted to sink down, to let sleep wash over him, to forget all of his troubles in merciful oblivion.
But the two colonists were very stubborn. They refused to let him collapse. He only wanted to go to sleep, to forget all of his troubles, but the two colonists were like doctors in a hospital, very stern, very patient, and seemingly determined to keep him on his feet.
Somehow they must have failed. They must have failed because when he became fully conscious again he was lying between cool white sheets, and a woman in a white nurse's uniform was bending over him. By straining his eyes he could see two men who looked like doctors standing just beyond her.
The two men appeared to be discussing him, but when he struggled to a sitting position and stared hard at them they came toward him with reassuring smiles, and one of them said: "Take it easy, now. You're going to be all right."
"I ... I must have passed out," he stammered. "I was ready to pass out before I started talking. Is this a hospital? I guess it is. I should have come here immediately. Forty hours in the desert and I arrive half-delirious and make a fool of myself."
"Take it easy," one of the doctors said. "You didn't make a fool of yourself. Quite the contrary."
Oh, brother, he thought. They're lying to me to spare me, or something. "I have a vague recollection of not being able to stand, of talking my head off and then collapsing and making a complete fool of myself, of accomplishing nothing at all. I swung hard at two or three people. I knocked one man down, flat on his back. But that was a crazy thing to do. It's no way to win the confidence or respect of anyone."
