He believed me.
It was just that simple. He believed me, because I suppose he knew, without knowing how he knew it, that it was truth. Humans are not incapable of communication; they are simply unaware of it.
I told him, also, that they were coming for me, that I had called them, and—regretfully—that he had better leave before they came.
"You said they weren't enemies or criminals. You were telling the truth, weren't you?"
"Yes, I was. They won't harm you. But they might...." I couldn't say it. I didn't know the words when I tried to say it. Might take you away with them ... with us....
"Might what?"
"Might ... oh, I don't know!"
Now he was suspicious again. "All right," he said. "I'll leave. You come with me."
It was just that simple. Go back with him. Let them come and not find me. What could they do? Their own rules would keep them from hunting for me. They couldn't come down among the people of Earth. Go back. Stop running.
We got into his car, and he turned around and smiled at me again, like the other time.
