One day a little boy dialed a telephone number and started to speak and he put part of his hand over the phone at the same time. He wanted to change the tone(音色，语调) of his voice. While all this was happening, a man who was working nearby watched carefully and listened with great interest to the conversation that followed:

＂Lady, can you give me the job of cutting your lawn(草坪)?＂

＂I already have someone to cut my lawn,＂ answered the woman at the other end of the phone.

＂Lady, I will cut your lawn for half the price of the person who cuts your lawn now.＂

＂I’m very satisfied with the person who is cutting my lawn.＂

The boy said, ＂Lady, I’ll even sweep the floor and the stairs of your house for free.＂

＂No, thank you.＂

With a smile on his face, the young boy thanked the lady and hung up the phone. The man then walked over to the boy and said: ＂Son, I like your attitude(态度). I’d like to offer you a job.＂

＂No, thanks,＂ said the boy.

＂But you’re looking for a job, aren’t you?＂

＂No, sir,＂ answered the boy. ＂I was just checking on my performance at the job I already have. I am the one who cuts that lady’s lawn!＂
