　　In my dual 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．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 medication 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 fastened 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 medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon．All of us who knew Tyler marveled at(大为惊讶)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 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 deadly disease eventually wore down even the likes of a little of a dynamo like Tyler．He grew quite ill and, unfortunately, so did his HIV-infected mother．When it became 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 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．"

The Making of a Surgeon

　　How does a doctor recognize the point in time when he is finally a “surgeon” ? As my year as chief resident(进修医生)drew to a close, I asked myself this question 　　1　　 more than one occasion．

　　The answer, I concluded, was 　　2　　．When you can say to yourself, “There is no surgical patient I cannot treat competently, treat just 　　3　　 or better than any other surgeon”－then, and not until then, you are 　　4　　 a surgeon．I was 　　5　　 that point．

　　　　6　　, for example, the emergency situations that we met almost every night．The first few months of the year I had 　　7　　 the ringing of the telephone．I knew it meant another critical decision to be 　　8　　．Often, after I had told Walt or Larry what to do in a particular 　　9　　, I'd have trouble getting back to sleep．I'd 　　10　　 all the facts of the case and, often, wonder 　　11　　 I had made a poor decision．More than once at two or three in the 　　12　　, after lying awake for an hour, I'd get out of 　　13　　, dress and drive to the hospital to see the patient myself．It was the only 　　14　　 I could find the 　　15　　 of mind I needed to relax．

　　　　Now, in the last month of my residency, 　　16　　 was no longer a problem．Sometimes I still couldn't be sure of my decision, but I had learned to 　　17　　 this as a constant problem for a surgeon．I knew that with my knowledge and experience, any decision I'd made was bound to be a 　　18　　 one．It was a nice feeling．

　　This all sounds conceited(自负的)and I guess it is－　　19　　 a surgeon needs conceit．He needs it to encourage him in trying moments when he's bothered by the 　　20　　 and uncertainties that are part of the practice of medicine．He has to feel that he's as good as and probably better than any other surgeon in the world．Call it conceit－call it self－confidence; whatever it was, I had it．
