Dear Mom,

    I guess you were very angry when you came home and saw my dirty room. You always shook your head gently but you said anything. You would take a look at me and then clean up the room in . When you said I didn't study hard enough, I often talked back and argued with you. I am sorry I to be a bad daughter in your eyes. But I didn't mean to make you unhappy. I want to be free with my own time. I promise I will try my best to get good grades. I hope you can me and I hope you will be a happy mom.

Yours,

Sally
