One of my. next-door neighbor is a sweet 92-year-old Polish lady. A few days ago, I came back from a trip. As I was 16 . my clothes in my room, I heard a(n) 17 , frantic(发疯的) knock on the door. It was 10:30 pm, and I wasn’t sure who it could be. I went downstairs and 18 the peephole, and saw that it was our sweet next-door neighbor. I quickly 19 the door, and she seemed really distressed and kept 20 , Please help me. I need your help. The fire alarm won’t go off. Please help me.” I 21 told her that everything would be okay, and 22 her to her house to see what was going on 23 the fire alarm. She 24 that the alarm had been going on and off inconsistently(反复无常的) for the past two hours, and that her 25 to call her daughter to come and fix it was fruitless. So I took a chair from her dining room table, 26 it, and looked at the tire alarm. After twisting the fire alarm off, I blew into it, because sometimes 27 causes it to make strange noises. She seemed 28 but was literally shaking out of fear. I asked her 29 she was okay, and she said she was 30 , so I gave her a hug. I felt her shaking in my embrace, and held her 31 for a few minutes until she stopped shaking and sighed a breath of relief. We then 32 and talked for ten minutes, until I felt that she was okay. and safe to sleep. She was so generous with 33 for being with her, but I thanked her for 34 me that hugs are indeed good tools! So, sometimes, a(n) 35 hug is a good and powerful way to hold someone going through a difficult period.
