Boy Giving Blood

There was a little girl named Liza who was suffering from a disease and needed blood 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 my sister Liza."
        As the transfusion took place, he lay in the bed next to his sister and smiled, as we all did, seeing the color
        return 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 so young, the boy had misunderstood the doctor. He thought he was
        going to give his sister all of his blood, then die.
