One possible version:
June3,Friday Fine
On my way home on the bus, I saw an old man get on with his grandson of about ten. He was carrying the boy’s schoolbag and violin. I gave my seat to the old man at once. However, the boy sat down first. The old man had to stand nearby. After a while, the boy shouted to his grandpa for water and then dropped the empty bottle on the bus.
When I saw this, I got very angry. I think the boy should not only respect and take care of the old man but also keep the environment clean.
