Robert was a student in a high school. His lather wanted him to study in a good university in the future. But the young man didn't study hard and liked playing cards. He had to go out after his parents fell asleep at night.
One night, when Robert came back, his father saw him. He was very angry and let him live upstairs. Of course it was not easy for him to go out again.
Last night Robert listened carefully. When he was sure his parents went to sleep, he went out to play cards. He won some money and was very happy. When he got back, he took off his shoes and was going upstairs. He heard a noise in his parents bedroom. Then he saw a man come out. He knew it was a thief. He stopped him at once. The man was very afraid and gave all the things back to him.
"Tell me how you didn't wake my parents up." said Robert, "Or I'll take you to the police station!"
