One possible version:
An Accident
One day, Daddy and I were taking a walk by the lake when a girl rode past at a very high speed. Then suddenly we heard a frightened scream followed by a big noise of something dropping into the water. We turned and found the girl struggling in the lake, crying for help. Daddy and I ran quickly towards her and pulled her out. We also managed to get her bike out. Almost immediately, the girl rode away even without saying “Thanks” . I felt quite disappointed at her behaviour .
We don’t help others for “thanks” , but nowadays many young people don’t know how to be polite . What a pity it is for our society and for our civilization! At the same time , I remembered stories where people offered their hand but were later accused of causing the accidents. How lucky we were! After all, we escaped being included in such stories .
