Starting with the Story of “Cujo”, the main problem is that Donna and his son, Tad, were trapped in a car in a remote repair shop, and a rabid San Bernard was attacking them. Donna reacts in a desesperated way and was really scared. His son was also really scared and he won’t stop screaming and crying.
They couldn’t go out of the car because Cujo wouldn’t go away, the weather was really hot and Donna and his son didn’t had water or food, they even slept there.
