My mother used to ask me what is the most important part of the body. Through the years I would 21 what I thought was the correct answer. When I was younger, I thought 22 was very important to us as humans, so I said, "My ears, Mommy." She said, "No. Many people are 23 . But you keep thinking about it and I will ask you again soon."
Several years passed 24 she asked me again. Since making my first 25 , I had often thought of the correct answer. So this time I told her, "Mommy, sight is very important to everybody, so it must be our eyes." She looked at me and told me, "You are 26 fast, but the answer is not correct because there are many people who are blind."
27 the years, Mother asked me a couple more 28 and always her answer was, "No, but you are getting 29 every year, my child." Then last year, my Grandpa died. Everybody was heart broken. Everybody was crying. My Mom looked at me when it was our 30 to say our final good-bye to Grandpa. She asked me, "Do you know the most important body part yet, my dear?"
I was 31 when she asked me this now. I always thought this was a 32 between her and me. She saw the 33 on my face and told me, "This question is very important. It shows that you have really 34 your life." I saw her eyes well up with tears. She said, "My dear, the most important body part is your 35 ." I asked, "Is it because it holds up your head?" She replied, "No, it is 36 on them a crying friend or loved one can rest their head. I only hope that you have enough 37 and friends that you will have a shoulder to cry 38
when you need it." Then and there I knew the most important body part is not a 39 one. It is sympathetic（有同情心的）to the pain of 40 .
