Problems with your brother??
This is usually normal. I´ve got a brother, and he´s really annoying. It´s because he is the smallest one and my father is normally protecting him... And he always get the things he wants to!!! Perhaps you have the same problem as me, and there are some tips to try to be in a good way with him.
One of the tips is to try to have a good relationship with him, telling him that you won´t say nothing he does bad to my father and viceversa. If you are exhausted and you can´t hold the truth more (and I understand) you can explain to your parents the problems you usually have and try to catch him inardventenly and show your parents you were telling the truth.
And I think that´s all. If you want another tips, you can comment on it and I will write the solutions out.
Bye!!
