A Letter from a Customer

"Dear Trampoline Manufacturer, My name is ......., and I am a 10th grade student at Oaks Christian High School in Westlake Village, California. I simply wanted to express my gratitude for your trampoline. I have enjoyed my trampoline very much... The following is a tribute to my trampoline.

... My trampoline is a safe place for me, and I can do whatever I want when I am on its surface. I can, sleep, read, laugh, cry, dream, hope, wish, jump, bounce, run, roll, fall, and just be me. I have so many wonderful memories on my trampoline. Mundane activities are made more wonderful when they are done on a trampoline. A book is more thrilling when read on a trampoline, joy is more tangible when expressed on a trampoline, and sorrow is less potent when confronted on a trampoline... I can lie on my back and daydream in the effulgence of the morning sun. In the peace of my backyard on my trampoline, I can enjoy solitude and do whatever activity is inspired by my mood.

One of the most endearing aspects of my trampoline is that no matter how I feel or what my mood happens to be, my trampoline always welcomes. It doesn't matter if I want to sing with joy or sob in anguish, my trampoline always welcomes me. When I am angry, I can fling myself about the trampoline until I collapse with exhaustion, and my trampoline will let me wear myself out without interposing. If I am worried I can hop distractedly around the trampoline, and it will gently lift my feet time and time again as I pace out my anxiety. When I am filled with inexpressible joy, my trampoline launches me into the sky, and when I fall back down to earth, my trampoline urges me to soar again.

... While some find trampolines dangerous and frivolous, I find them exciting and important. On my trampoline, I have the freedom to do anything and feel anything. My trampoline is a tiny alcove in a busy world. As I climb onto my trampoline, I find respite from my worldly cares. Homework fades into the background as I get a little time to be alone. Free from worries and liberated from concerns. I can slip away into a quiet world on my trampoline."
