There is many rules in my family. One of them is that me have to go to bed before 10 pm. I agree with this a rule. I think students like me need to get lot of sleep. Then it is easier for me to concentrate(集中注意力) and listen the teacher in class.I always obey this family rule，but I am unhappy about other rule in my home. The rule is that I'm not allow to have a pet dog. My parents are afraid that I will spend too many time on the dog，and I think that a pet dog is just like a good friend .I can talk to it when I feel alone or unhappy，so I will have a talk with my parents later.
