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. But they said nothing and went to eat in the house. The landlord was quite pleased.
