　　Tyler was born infected with HIV and his mother was also infected. From the very beginning of his life,he was dependent on medications (药物) to enable him to survive.When he was five, he had a tube surgically(外科手术上) insertedin a vein（静脉） in his chest.This tube was connected to a pump, which he carried in a small backpack on his back. Medications were connected 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 findhim playing and racing around his backyard, wearing his backpack and dragging his tank of oxygen behind him in his little wagon（小推车）.All of us who knew Tyler were amazed at his pure joy in being alive and the energy it gave him. Tyler'smom often made jokes on him by telling him that he moved so fast 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 terrible disease eventually wore him down. He grew quite ill and, unfortunately, so did his HIV - infected mother. When it became clear 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(召唤) me over to his hospital bed and whispered, "I might die soon. I'mnot 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 mare she can find me."
