Today, bone marrow must be drawn again. However, because her heart is weak, it must be done without anesthesia. Knowing that even adults find this treatment difficult to endure, Guest predictably cried and refused.
He looks down at his gloved hands, then pulls them off. With his bare hands, he wipes away the tears streaming down Guest's cheeks.
