I have worked with numerous children infected with the virus（病毒） that causes AIDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, 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 surgically¹ inserted in a vein²（静脉，血管） 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（连接到） 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 racing³ around his backyard, wearing his medicine-laden（装满的，负载的） backpack and dragging his tank of oxygen behind him in his little wagon⁴（货车，四轮马车） . All of us who knew Tyler marveled（惊讶，好奇） at his pure joy in being alive and the energy it gave him. Tyler's mom often teased（取笑） him by telling him that he moved so fast she needed to dress him in red. That way, when she peered（凝视） through the window to check on him playing in the yard, she could quickly spot him.

This dreaded⁵（令人畏惧的，可怕的） disease eventually wore down（使精疲力竭，使消瘦） even the likes of a little dynamo（发电机，电动机） like Tyler. He grew quite ill and, unfortunately, so did his HIV-infected 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's he would be with him soon in heaven.

A few days before his death, Tyler beckoned⁶（示意, 召唤） 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. "
