                                                       No More Chores, Please!

     Sam hated doing chores. And he had many chores. For example, on Mondays, Wednesdays

and Fridays he took out the trash. And on the weekend he always washed his father's car. He also

cleaned his own room once a week. What a chore that was ! Sometimes he even had to look after

his little sister and brother.

     Sam had a foreign friend at school. His name was Kumar. Doing chores in Kumar's family was

very different. In the house only the girls did chores. His sisters made all the beds and cleaned all the

rooms too, even his bedroom. His mother always cooked the meals, and his sisters helped her mother.

So when Kumar talked to his friend Sam about chores, he felt very lucky. One day, Sam had an idea.

He asked Kumar,"Could I borrow your sisters?" He wanted them to help him clean his room, but

they refused. Instead, they asked Sam to teach their brother how to do chores, so he could make his

own bed.

     Sam and Kumar are very good at science. They are going to be scientists after university. They

want to make a robot to do the chores. Then everyone-mothers and father, sons and daugters will

be happy!
