      In my profession as an educator and health care provider, I have worked with numerous children

infected with the virus that causes AIDS.The relationships that I have had with these special kids have

been gifts in my life.They have taught me so manythings, but I have especially learned that great courage

can be found in the smallest of packages.Let me tell you about Tyler.

    Tyler was born infected with HIV: his mother was also infected.From the very beginning of his life, he

was dependent on medications to enable him to survive.When he was five, he had a tube surgically

inserted in a vein in his chest.This tube was connected to a pump, which he carried in a small backpack

on his back. Medications were hooked up to this pump and were continuously supplied through this tube

to his bloodstream.At times, he also needed supplemented oxygen to support his breathing.

     Tyler wasn't willing to give up one single moment of his childhood to this deadly disease.It was not

unusual to find him playing and racing around his backyard, wearing his medicineladen backpack and

dragging his tank of oxygen behind him in his little wagon.All of us who knew Tyler marveled at his pure

joy in being alive and the energy it gave him.Tyler's mom often teased him by telling him that he moved

so fast that she needed to dress him in red.That way, when she peered through the window to check on

him playing in the yard, she could quickly spot him.

     This dreaded disease eventually wore down even the likes of a little dynamo like Tyler.He grew quite

ill and, unfortunately, so did his HIVinfected mother.When it became apparent that he wasn't going to

survive, Tyler's mom talked to him about death.She comforted him by telling Tyler that she was dying

too, and that she would be with him soon in heaven.

     A few days before his death, Tyler beckoned me over to his hospital bed and whispered, "I might die

soon.I'm not scared.When I die, please dress me in red.Mom promised she's coming to heaven, too.I'll

be playing when she gets there, and I want to make sure she can find me."
