Differences of Opinion

I have lots of different opinions and attitudes of my brother that I cannot understand!
As my parents both work part time, I'm the cook of my family. I've been cooking dinner for 6 years or so. And I have to do the house chores too.I like cooking and it is not a big problem for me but sometimes I get too tired of doing all my shool works, part-time job and house chores.
 I hate when my brother, who doesn't go to school, does never help me doing any of those house chores. And even worse, he messes up the living room and never cleans the room. He often takes his friends to his room and chat with them that keeps me awake because they are loud.
My brother and I are good friends but he is so annoying in that way.
