Self Appraisal a short story

A little boy went to a telephone booth which was at the cash counter of a  store and dialed a number. The store-owner observed and listened to the  conversation:  

Boy                 : "Lady, Can you give me the job of cutting your lawn?
Woman           : (at the other end of the phone line) "I  already have someone to cut my

                         lawn."
Boy                 : "Lady, I will cut your lawn for half the price than the person who cuts your

                          lawn now."
Woman           : I'm very satisfied with the person who is  presently cutting my lawn.
Boy                 : (with more perseverance) "Lady, I'll even sweep the floor  and the stairs

                          of your house for free.
Woman           : No, thank you.

With a smile on his face, the little  boy replaced the receiver. The store-owner, who was listening to all this,  walked over to the boy. 

 Store Owner   : "Son... I like  your attitude; I like that positive spirit and would like to

                                offer you a  job."
Boy                 : "No thanks,
Store Owner   :  But you were really pleading for one.
Boy                : No Sir, I was just  checking my performance at the job I already have.

                         I am the one who is  working for that lady I was talking to!"
