I'm really tired

I'm really tired today. I was up at 6 am. I had to make the little kid breakfast. Take him to school. I had to run errands. Then go to work. I was having a ok day today. until my brother show up. Telling me what to do. Why is he telling me what to do. He just piss me off at night. Why does he have to show up. Then he told me to drop him off first. Before I pick up the little one. I told him the little needs to be pick up and put to bed. We get back to the house and he telling me what to do again. The little one told him off. Omg I was shock. The little one told him to mind his own business. I'm more responsible then him. Stop telling her what to do. My brother shut up after that. He should worry about his life not mine. I know what to do with my life. I'm tired!
