In a small village, there is a house with 1,000 mirrors.
A little dog learns about this place and wants to visit it one day. When he gets there, he is very happy and goes into the house. He looks into the mirrors with his ears up high and his tail wagging (摇摆尾巴) as fast as it can. It is strange (奇怪) for him to see 1,000 other happy little dogs with their tails wagging just as fast as his. He smiles (微笑) and 1,000 great smiles smile back to him, they are warm and nice. As he goes away from the house, he thinks to himself, "This is a good place. I will come back and visit it often."
In the same village, there is another little dog who often gets angry. The dog wants to visit the house too. He goes into the house with his head down. When he sees 1,000 angry dogs looking back at him, he growls (低沉咆哮) at them and is afraid to see 1,000 little dogs growling back at him. As he leaves, he thinks to himself: "____21____ I will never go back there again."
Mirrors can't change (改变), but faces can. What kind of face do you have today?
