Mary and Peter were having a picnic with some friends near a river when Mary notice an object overhead. "Look!" she shouted to her friends. "That's a spaceship up there and it's going to land here."

Frightened by the strange silver-colored spaceship, most of the young people got in their cars and drove away quickly. Peter was fond of Mary and always stayed close to her. They, more curious than frightened, watched the spaceship land and saw a door open. When nobody came out, they went to the spaceship and entered inside. Peter followed Mary into the spaceship and did not hear the door closed behind him. The temperature fell rapidly and the two young people lost consciousness.

When they woke up, they were surprised to see that they were back by the river again. The spaceship had gone. Their car was nearby.

"What happened?" asked Mary.

Peter scratched (抓) his head, saying slowly, "Don't ask me. Perhaps we had a dream. Did you...Did you see a spaceship?"

"Yes," said Mary. "And we both went into it. Then..." she looked at her wrist. "That's funny. My watch has stopped. Oh, well, come on. It's time to go home."

Driving about fifty meters, they found their way blocked by a thick wall made of something like glass. They got out of the car and tried to find their way round the wall but discovered that they were inside a circular wall. It was like a mirror and prevented them from seeing through it.

On the other side of the wall, strange creatures walked past slowly. A few stopped to stare through the wall and read a new notice which, translated into English, said: "New arrivals at the zoo: a pair of Earthlings in their natural surroundings with their mobile house."
