Every day，Vickey traveled by bus between her office and home．She noticed something special about the bus driver．Whenever the passenger （乘客）got on the bus，he would smile at them．

However ，Vickey also noticed a passenger who never smiled back at the driver．It seemed that he never had any clean clothes．He often made big noises when he coughed．Every time he got on the bus，he made the other passengers give up the seat to him in a loud voice．But the driver still smiled at the passengers．Instead，the "noisy" man seemed to never see the smile．

This got Vickey more interested．Once， she asked the driver，"Sir， may I ask you a question？Why don't you throw that noisy man out of bus？"

The driver looked at Vickey and said"He's my guest．"

"Then take back your smile at least．Don't be so nice to him!"

"Let me tell you about my dog，" the driver said patiently．"Each time the moon shines，my dog barksg（狗叫） at it crazily．"

Hearing this，Vickey was confused and said，"Sorry，but I'm not sure what you're trying to tell me．"

The driver said"It keeps barking， but the moon still shines．"
