Blood brother
True story:An eight-year-old boy had a younger sister who was dying of leukemia. His parents explained to him that she needed a blood transfusion and that his blood was probably compatible. They asked if they could test his blood. Sure, he said. The results showed that his blood would be a good match. Then they asked the boy if he would give his sister a pint of blood, that it could be her only chance at living. He said he would like to think about overnight.
