I'm sorry but I hate my little brother
Why do you hate him?
He asked me for a train fare, the little rat
Families should work things out. It's not ok to call your brother names over small things. You're expected to support your siblings.
He also asked me money for his ballet class.
It just looks like your brother is looking for help in pursuing his hobbies. I believe you should be a little more responsive and kind to him, because he needs to be encouraged at such an age. How about trying to compromise, like he can do your chores and you can pay for his fare?
