The boys had to sit by the door and have lunch on the ground. The landlord was afraid that other people would see the bad food for the boys. So with a smile on his face he said to them： “Boys， go and eat in the house. This is for your food. If you eat here by the door， the dogs will bite you.” The boys were surprised.

When they walked past the landlord‘s room， they looked in through the window. What do you think they saw there? They saw a big table with white bread and all kinds of good food on it. The landlord and his family were sitting around the table and eating their dinner. But the food for the boys was bad. The boys were very angry. They wanted to teach the landlord a lesson. So they decided to plant his garlic upside down. And that was what they did the next day. A few days later the garlic was coming out everywhere but not in the landlord‘s fields. The landlord was very surprised and asked the boys why this was so. “The garlic is afraid that the dogs will bite it，” the boys answered. The landlord asked the boys to come because ________.
