"Don't take it offensively," I said. "But you really do. Also your arm motion is not good." He was so angry that it was almost funny. Now I was sorry I had spoken, because the girl might be a close friend of his and she might take offense. "Maybe you would like to show me how it's done," Ken said hotly. "I could make it worth your while. Suppose we race two lengths. For ten dollars." "That's not fair, Ken," the girl said. I could see that she didn't like the way he was taking it, so that was all right. But I hesitated. I didn't have ten dollars. On the other hand, I had been watching these people swim. It was an easy way to make ten dollars, since I had no other means of getting money. There was the hundred dollars which I had taken from a man on the road the day I came into town, but that money was gone. "Come on," I said, and started walking to the end of the pool. When I got there I bent and dipped one foot into the water. It was colder than the water I had been used to, and not quite as heavy, somehow. I pulled my foot out quickly and everybody laughed, except the girl. "This isn't right," she said. She turned to me. "You don't know who Ken is, apparently." "You are very kind," I said. I smiled at her and she smiled back. She had blue eyes. By that time the pool had been cleared. Everybody was out of the water and standing at the edge. Ken said, "Whenever you're ready." "I am ready now," I said. And immediately one of his friends gave the signal, "Go!" Ken jumped in first. Then I dived in. Once in the water it did not feel so cold nor so light. I swam down to the other end and turned around and swam back. When I climbed out, Ken was just making his turn at the far end. Everyone was looking at me very strangely. Ken came out rubbing his shoulder. "Must have pulled a muscle," he muttered. "In that case I wouldn't think of taking your money," I told him. "I don't believe I've seen you around before," he said. "You've got to have a card to swim here, you know.'
