| Tick, tock, tick, tock. I'm sitting here, watching the movements of my existence pass slowly away. My house has been 1 for such a long time and I'm lonely and forgotten. Sitting here, by myself, all that I can do is 2 and think about my past. I could tell you stories that only 3 would know. But walls can't speak. I came to this place many years ago, along with an old man... 4 , he was with me for only three short years before he passed away.... For a time, I was left alone, while people came and 5 the house.... Then, one day a nice couple moved in with a young son. From the beginning, their son Danny liked to stay with me, and I was completely 6 with him. He always looked as if he loved the stories I told, most of which began with "Back in my day..." and "When I was younger..." I sometimes had the kind of idea that he didn't really understand what I was saying, but it felt good to be 7 .... When Danny went off to college, my heart broke. Soon afterwards, 8 sold the house.... New owners came and 9 . Then, one day it so happened that I was in when a new family was moving into the house. You can't imagine my 10 when, unexpectedly, Danny walked through the front door. He had a 11 and kids now. I was so overjoyed when I saw him that I put all my 12 into my daily activities.... I spent the next twenty years watching his kids grow up, with a mixture of pride and anxiety about what would happen next. The kids finally became 13 and Danny sold the house. That was about five years ago.... Some of the local kids have started the rumor (谣言) that the house is haunted (闹鬼的)-and, in a way, it is. It is haunted by 14 of all the people who have lived in it. Every second has impressed me so much. I have been counting them down and they are almost up for me.... I hope that someday somebody will 15 me, and call on me again. Maybe then I'll get a new home and a chance for a whole new set of memories. | ||||
