My little sister I have a little sister, her name is yuanyuan.She can sing very well. Because of my grandpa, yuanyuan comes to my home to live for one day.She really likes my little dog Goofy very much.She always plays with him all day long.She also runs on the running machine again and again , this makes her really tired.We sleep together last night , but my bed is too small so we can barely sleep in one bed.She will go back this afternoon. I hope my little sister can come more often. Thank you very much!
