What do you think of swapping lightbulbs in my room with my brothers working ones while he's at school?
That is mean. Why are you going to do that?
I hate him and I thought it would be a sweet revenge
Is there a good reason to hate your brother? Hate is a powerful emotion, and is one that you should rarely feels towards family. You should talk with him and tell him what's your problem with him.
Nah, it's not worth talking about it. Revenge feels better than anything.
Revenge is not a good way to deal with emotions. You will have a better relationship with him if you stop hating him.
