A big company wanted a clerk,so John went there. In the interview,the director asked him a question. “Who paid for your school?” “My mother paid for it by washing clothes.”

Hearing this,the director asked John to show his hands. John showed a pair of hands that were perfect . The director said,“When you go back today,go and clean your mother’s hands,and then see me tomorrow morning.”
