The worse mistake that i have ever made :(

Friday 19 August was the date for my Chinese compo exam .A day that i will want forget. We have to select a topic to write about. I have choose the topic is about the a experience i have learnt after a mistake i made . I have decided to write me having a bad habit of littering then i got worse i even started throwing things from high building. But i did not pay good attention to the word one. Thus i have made a very big mistake, i have wrote out of point for the compo. I was very disappointed with myself . That day was a terrible day for me.
