Ways to get out of trouble #1:
Dont try to explain to adults that you are ignorant when you made a mistake. They treat you as a young adult (at least in the eyes of the teachers anyway) and in the adult world, if you made a mistake, there's no coming back of saying you did not know how to do it. If you cannot rebut their accusation or you are not eloquent enough, you are as well as dead.
Solution: Admit it cheesily and maybe crack some jokes.
Ways to get out of trouble #2:
Do you homework! (Just for those teachers who might send you to SIP or scold you severely).
Ways to get out of trouble #3:
There are bounds to be people saying that you are wrong in the "adult" world. No matter how hard you try to persuade them you are right, they won't listen.
Solution: Believe in what you think anyway and "accept" what they told you to believe in. See, this is the part where the chinese word "敷衍" comes in. For those non-chinese, it means when people told you to do something which you don't like, you did it anyhow to stuff the person's mouth up. (note: this does not apply to crime like arson, murder or other stuff.)
P.S dont take this too seriously :D
