There are four kinds of horses! The first kind of horse is whipped by the master, will follow the master’s order. If the master wants it to go to the right it won’t dare go to the left. It only does what it is told. The second horse is the smart one. Before the master raises his hand, it gallops away. The third kind of horse has no any feeling. No matter what the master does, it was just will not move. The horse completely blocks its ears and eyes. The fourth horse is a really clever one; it always understands what the master wants. Which type of horse do you belong to, my friend?
