Today my mom and I had a quarrel because she said I didn't study hard, so I can't play computer. I really studied hard and I thought that I can control my own time, but Mom even didn't like if I spend too much time at my writing.

I knew it is certainly not right to yell to Mom, but I did that because I was very angry, and my tears almost came out. I slammed the door.

We were better in the morning, but I still didn't now how to tell her.
