The distress of being a sister

Some people, without sisters, want to be sisters, while others have sisters and don't want to be sisters. That's what I am. Why? Let me show you.

? When you become a sister, you must let her go unconditionally. If you have difficulties, you should hide them in your heart. As long as you quarrel with your sister, it's all her fault, and my parents unconditionally say it's your fault. What I hate most in my life is: what does he know when he is young? Can't you let him go? But what you don't know is, have I grown up? Am I an adult? No, I am also a little girl who is only 15 years old. I don't want to be rational about everything. I have done a lot for you. I am sensible enough, but I don't want to be sensible anymore, because I know I can only get no candy. I don't like my sister. Not because he wanted unconditional comity when he was young. What I often say to my mother is, why do people do this to me? In fact, what I want to say in this world is why I can't get recognition from my family. I took 120 math in grade two, and I have only been able to take 90 math. But judging from my efforts, I reached the first place in every grade. However, mom and dad turned a blind eye. No big deal. My sister is doing math homework at school, and I don't know how much I praised her for 100.

? I don't like my sister.

I don't like that mother.

I don't like my father.
