Lie to my sister. My sister asked me to write a 500-word review.

Dear sister:

I shouldn't have lied to my sister, I'm sorry! What I have committed is a serious matter of principle. Because of my mistake, it is also a kind of injury to you and an irresponsibility to my parents. My bad behavior is not challenging your discipline. Afterwards, I thought calmly for a long time. The mistake I made this time not only brought me trouble, but also delayed my study. At the same time, I sincerely hope that you can continue to care and support me, but deal with my problems as appropriate. I have deep feelings for you, and I will appear in front of you with a new look in the future, instead of giving you and your parents a dark touch. However, facts have proved that it is not enough to devote yourself enthusiastically, work hard and study hard, but also to have a clear political mind, a sense of overall situation and a sense of discipline, otherwise you will lose your way in your study and the country and the school will suffer losses. At the same time, I sincerely hope that you can continue to care and support me, but deal with my problems as appropriate. I know I have to bear the responsibilities I can't afford, especially the main responsibility I can't shirk in this mistake. I know you are angry with my question, too. Be alert when you are ashamed, forge ahead when you are ashamed, mend your ways when you are late, turn shame into motivation and study hard.

Please forgive my sister again!
