Long ago in a small village, there was a place known as the House of 1,000 Mirrors.

A happy little dog decided to visit this place. When he arrived, he jumped up the stairs of the House. His ears were raised high and his tail was wagging as fast as it could. To his surprise, he saw 1,000 happy dogs in the mirrors. They wagged their tails as fast as his tail. He smiled a big smile. He saw 1,000 friendly smiles. As he left, he thought to himself, "This is a wonderful place. I will come back again."

In the same village, there was another little dog. He was not happy all the time. He also decided to visit the House. He climbed the stairs slowly. He hung his head low when he looked into the mirrors. He saw 1,000 unfriendly dogs staring at him. He shouted at them. He was scared to see 1,000 little dogs shouting back at him. After he left, he thought to himself, "That is a terrible place. I will never go back there again."

In fact, all the faces in the world are mirrors. When you smile at others, they'll smile at you, too.
