My brother Tom was very selfish when he was little boy. He did not want share things with

other people. For example, when he bought a chocolate cake, he put them in a secret place,

that I couldn’t find. Then he ate it all by himself. He never helped other. He said he is busy.

In other words, a game of tennis made him very busy. He did not care if something that he did

it made people angry. For instance, one night he played strongly and loud music till four o’clock

in the morning. But he is difference now. He often helps grandma with houseworks, helps mom

with cooking and helps his classmates with their lessons.
