My sister, a primary school teacher, was informed by one of her pupils that a bird had built its nest in the tree outside the classroom. 

What kind of bird?" my sister asked. 

"I didn't see the bird, ma' am, only the nest," replied the child. 

"Then, can you give us a description of the nest?" my sister encouraged her . 

"Well, ma'am, it just resembles your hair. " 

我姐姐是一位小学老师。一次一个学生告诉她说一只鸟儿在教室外 的树上垒了个窝。 

“是什么鸟呢？”我姐姐问她。 

“我没看到鸟儿，老师，只看到鸟窝。”那孩子回答说。 

“那么，你能给我们描述一下这个鸟巢吗？”我姐姐鼓励她道。 

“哦，老师，就像你的头发一样。”
