in this town. man 500 e theme jobs change 口 (28~30) Dear Bacon, When we first met on the street, you were small and sweet. Every weekend, we jogged together in the morning. We also played baseball in the park. I threw the ball and you caught it. At night, you sat beside me when I did my homework. Before I went to bed, you always gave me a good night kiss. I felt lucky to have you with me. However, a year later, everything changed. You have grown too big and become very strong. Jogging with you is dangerous. You often dash and pull me into the trees. When we play in the park, you always bite other kids and dogs. At night, you bark a lot. Also, at home, you break every piece of glass and scratch the sofa. You're tearing the house apart. Tomorrow I mus take you to Dr. Jones. I know he looks serious, but my parents and I believe he will turn you into a good dog. So have sweet dreams tonight. Love you, Jimmy dash bark scratch B 28.
