Children with chaotic reaction asked,"What pay?"

Robert said," Here, we have not came to work for you, here we have came to learn how to make money."

Mike's dad replied,"look children I am not going to teach in the way how you did in school, just sitting and listening. I will teach you in the way how life teaches us. So, is that deal fine?"

Children nodded their heads up and down which indicates that they are satisfied with the deal.

4 weeks passed children worked in Mike's father office, they only did small-small works like cleaning the  table, window, book shelves,etc. For each hour they were paid 10 

cents.

After 4 weeks, Robert said to Mike,"I will be not coming to your father's place from this Saturday onwards because your father is only getting his work done and even not teaching us. And for these 10 cents coins I am wasting my Saturday at your's father...
