There was a man called luke who lived in a little cottage beside a mountain. He also lived near a village. One day, he decided that he was going to steal other people's money. He went to all the houses in the village and said to the people who owned the houses, "My daughter is very sick. please, will you give me ten pounds? I will give you twelve pounds back." So that's what he did and said to all the people in the village. After all that, he went home with his pockets full of money, feeling pleased with himself. The next day, he spent all the money on drinking and eating and buying fancy clothes, but he forgot his promise that he was going to give twelve pounds back. He never returned to the people's houses. All the home owners bumped into each other, talking about the man who asked for ten pounds and promised to return twelve pounds to them. They went to luke's house and said, "You lied! you don't even have a daughter!" They never got the money back, because luke spent it all. Soon, luke got married and had a daughter. One day she got sick. Luke went to the people again, but they never gave him anymore money, because they didn't trust him anymore. 
Liars cannot be trusted.
