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.
