In the last fifty years, a lot of people have left Europe and have gone to live in Australia. One of them was a Hungarian man. He lived in Australia for a long time, and after that, he had a lot of good friends.
He always said to them, “Australia's beautiful, but Hungary's beautiful too.”
Then one year he said, “I'm going to go back to Hungary now to visit my old home.”
All of his new friends said to him, “We want to go with you, because Hungary's a beautiful country, and we want to see it too.”
The Hungarian Australian took all his friends from Sydney to Rome in a big plane, and then they went from Rome to Budapest in a train, because they wanted to see the mountains, and the villages, and the towns.
They stayed in Budapest for four days, and they liked it very much. One day they went to the zoo in Budapest and saw two kangaroos there.
The Australians were very happy, because kangaroos come from Australia. They said to the animals, “Come here, old friends! Come and see your Australian brothers!” But the kangaroos did not move.
But then the Hungarian Australian spoke to the animals in Hungarian. “Come here!” he said, and both the kangaroos ran to him.
The other Australians laughed and said, “Look at that! They're Australian, but they only know Hungarian!”
