My brother Dave is 11 and I am 4 years older. He and I always get into fights. Whenever he does something wrong like hitting me or making my room dirty, he never gets into trouble. He doesn't even have to say sorry to me. But when I do these, my parents always ask me to say sorry. It's so unfair!
I tried talking to my parents about this and all they said was that they would change. However, they never did anything. Sometimes I talk with my friends on the computer, but my parents only allow me to use the computer for 30 minutes every time. Dave can use it for three hours.
I talked to my friends about this. They advised me to talk to Dave and be nice to him. I tried but it didn't work. Dave made my life terrible! My dream is that my brother and my parents could understand me. What should I do for that?
