One evening two young men were walking in the street together. They tried to find a chance to steal
something. The clock struck twelve. Most of the people went to bed. Quickly they came to a house and
it seemed that everyone in the house had fallen asleep. Standing at the front gate, one said in English to
the other in a low voice,"You wait here. I'll go around to the back door and then get into the house."
Suddenly out of the house ran a dog, barking at them. The two men were very frightened and ran away
as fast as they could. Finally, they stopped at a lonely place. The man said breathlessly, "It's too bad. I
hadn't expected that the dog could understand English."
