Like most elementary schools, it was typical to have students in and out of the health clinic throughout the day. As the principal, my office was right next door to the clinic, so I often dropped in to lend a hand and help out with the hugs.

   One morning I was putting a Band-Aid on a little girl's scraped knee, who had beautiful blonde hair. I found her a warm sweatshirt and helped her pull it on. "Thanks for taking care of me," she whispered to me.

   It wasn't long after that when I ran across an unfamiliar lump under my arm, a very bad kind. I wondered whether or not to tell the students about my disease. The word cancer seemed so frightening, when it became evident that the children were going to find out one way or another, I decided to tell them myself, when I gave them a chance to ask questions, they mostly wanted to know how they could help. I told them that what I would like best would be their letters, pictures and prayers.

   Suddenly, my little blonde friend walked to me and threw herself into my arms. "Don't be afraid, Dr. Perry," she said earnestly. "I know you'll be back, because it's our turn to take care of you."

   When I was in hospital, the letters and pictures kept coming until they covered every wall of my room. Then the kids traced their hands onto colored paper, cut them out and glued them together to make a rainbow of helping hands.

   At last I was well enough to return to work. As I headed up the road to the school, I was suddenly overcome by doubts. Then I noticed a big sign hanging in front of the main door of the school. "Welcome Back, Dr. Perry," it read: As I drew closer, everywhere I looked there were pink ribbons. My blonde friend was first in line to greet me. "You're back, Dr. Perry, you're back!" she called. "See, I told you we'd take care of you!"
