【答案】An Unforgettable Thing
    Life is full of the unexpected.I'll never forget the experience that I had last year.It was a sunny afternoon and on the bus，I saw an old man get on with his grandson of about ten.He was carrying the boy's schoolbag and a 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.
