She said; "No. many people are deaf and can’t hear anything but they live normal lives. But you 33  thinking about my questions and I will ask you again soon. "

Several years passed before she asked me again. This time I told her_:“Mommy.  34 is very important to   35  , so it must be our eyes. "

She looked at me and told me: "You are learning fast, but your  36  is not right because there are many people who are blind and who arc happy and healthy all the same.”

Everybody was crying. My mom asked me: “Do you know the most important body

“Is it because it holds up (支撑)my head?”I asked.

"No, it is because it can hold a head of a friend or a loved one when they 39 ."

she answered. “ Everybody needs a shoulder to cry on sometime in life. I only hope that you have enough love and friends in your life. So, you will  40 have a shoulder to cry on when you need it."
