So you think I’m courageous?” she asked.
“Yes, I do.”
“Perhaps I am. But that’s because I’ve had some inspiring teachers. I’ll tell you about one of them.
Many years ago, when I worked as a volunteer at Stanford Hospital, I got to know a little girl named
Liza who was suffering from a rare and serious disease. Her only chance of recovery appeared to be a
blood transfusion from her five-year-old brother, who had miraculously survived the same disease and
had developed the antibodies needed to combat the illness. The doctor explained the situation to her
little brother, and asked the boy if he would be willing to give his blood to his sister. I saw him hesitate
for only a moment before taking a deep breath and saying, ‘Yes, I’ll do it if it will save Liza.’
“As the transfusion progressed, he lay in a bed next to his sister and smiled, as we all did, seeing
the color returning to her cheeks. Then his face grew pale and his smile faded. He looked up at the
doctor and asked with a trembling voice, ‘Will I start to die right away?’
“Being young, the boy had misunderstood the doctor; he thought he was going to have to give
her all his blood.
“Yes, I’ve learned courage,” she added, “because I’ve had inspiring teachers.”
