What the doctor has to say is shocking: this family has learned a valuable lesson!
The message of this short film is clear: any prejudice based on these aspects (as in this case the color of the skin) is shameful. In the situation described, a family is sitting next to a man and being unfriendly to him. Shortly after, it is revealed by the doctor that he was the one to donate bone marrow that allowed the child to live peacefully. Unfortunately this, which seems a paradoxical situation, is still real and happens in everyday life and in subtle forms, and for this reason difficult to eliminate.
