I'm help my older sister clean her bedroom and I also play with my dog in back yard

After class I took bus home and I go to kitchen to find something to eat. Later my older sister came home and I went her bedroom to help her clean the room. Her had so many stuff and I have no idea, I just want to put everything on the garbage. However those stuff wasn't my, I couldn't bring those things drown garbage. I had to map her table stuff and clean other thing. And than I brought her dirty clothes downstairs for my aunt to clean her clothes. When I finish work, I took my dog go to back yard play with me. I drew the ball and he ran to get ball for me. I ran a little bit with him. Today I had a bad luck because my dog bite my butt. My butt was painful. I didn't mad him because I think he mistakes. It wasn't his fault.
