For the past few years, I've noticed that I'm constantly being essentially swept under the rug when it comes for things between me and my twin brother. I'm always being punished when I mess up, but he's getting much much lighter punishments for doing things that are arguably worse. He always gets the say in arguments, and when he doesn't get what he wants, he's all pissy until the next day. I'm incredibly tired of this, because I just want things to be fair in my house. What should I do?
