In Dr. Seuss’s “Green Eggs and Ham,” characters play pivotal roles in the narrative. Sam-I-Am, an enthusiastic promoter of the titular dish, embodies the highest level of closeness to the topic, relentlessly pursuing the unnamed man to try the delicacy. The unnamed man, initially resistant, serves as a contrast, highlighting the absurdity of Sam-I-Am’s persistence. Goat, Mouse, and Turtle, with their varying degrees of openness, add depth to the story, showcasing different perspectives on the topic.
