     Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy

Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. "Yes, honey. Of course."

she said.

     "Can we write him a letter?"

     She paused, the longest pause of my short life, and answered, "Yes."

     My heart jumped."How? Does the mailman go there?" I asked.

     "No, but I have an idea." Mom drove to a party store and returned with a red balloon. I asked her what it

was for.

     "Just wait, honey. You'll see." Mom told me to write my letter. Eagerly, I got my favorite pen, and poured

out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Mom

was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still

alive. I gave the letter to Mom. She read it over, and a smile crossed her face.

     She made a hole in the corner of the letter where she looped (缠绕) the balloon string. We went outside

and she gave me the balloon. It was still raining.

     "Okay, on the count of three, let go. One, two, three."

     The balloon, carrying my letter, darted upward against the rain. We watched until it was swallowed by the

mass of clouds.

     Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No

matter what he suffered, he'd persevere, dart up, and finally transcend (超越) this cold world and his sick

body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray

and white and I prayed that his strength was hereditary. I prayed to be a balloon.
