     A German taxi-driver, Franz Bussman, recently found a brother who was thought to have been killed

twenty years before.

     While on a walking tour with his wife, he stopped to talk to a workman. After they had gone on, Mrs

Bussman commented on the workman's close resemblance to her husband and even suggested that he

might be his brother. Franz poured scorn on the idea, pointing out that his brother had been killed in action

during the war. Though Mrs. Bussman was fully acquainted with this story, she thought that there was a

chance in a million that she might be right.

     A few days later, she sent a boy to the workman to ask him if his name was Hans Bussman, Needless

to say, the man's name was Hans Bussman and he really was Franz's long-lost brother. When the brothers

were re-united, Hans explained how it was that he was still alive.

     After having been wounded towards the end of the war, he had been sent to hospital and was separated

from his unit. The hospital had been bombed and Hans had made his way back into Western Germany on

foot. Meanwhile, his unit was lost and all records of him had been destroyed. Hans returned to his family

home, but the house had been bombed and no one in the neighborhood knew what had become of the

inhabitants. Assuming that his family had been killed during an air-raid (空袭), Hans settled down in a Village

fifty miles away where he had remained ever since.
