    My mother used to ask me what the most important part of the body was. I got different answers at different ages.

    When I was young, I thought sound was very important to us, so I said, "My ears, Mom. "But she shook her head and said no. Several years passed, and she asked me again. I believed that I got the right answer after thinking it over. So I told her, "Sight is very important to everyone, so it must be our eyes. "But she told me I was wrong. I tried many times after that, but her answer was always the same. Until last year, my grandma died. Everybody was crying, and everybody was hurt. My mom looked at me and asked me with tears in her eyes, "Do you know the answer now? "I was surprised when she asked me this question then. "My son, the answer is your shoulder. Everyone needs a shoulder to cry on(倾诉).

    Finally, I realized all she hoped is that I can have enough love and friends so that I will have a shoulder to cry on when I need it.
