Last night, I went home late and was really 5 from practice. However, I didn't forget 6 my homework. I had dinner and did it at the same time. When I nearly finished it, suddenly I dropped some meat on my paper. I didn't know 7 to do. It was too late. I had no time to do the homework on 8 piece of paper. So I just put my paper on the table and went to bed. My dog Max loved meat very much and it jumped up onto the table and ate my 9 . My teacher said it was an old story. I 10 know many students say it all the time. But this time, it's true! Who can believe me? | |||
