I used to think this character didn’t want to try Green Eggs and Ham because he was grumpy. Sam-I-Am needed to stop acting like a caffeinated car salesman.
Then I realized the truth. He isn’t annoyed. He’s afraid. Afraid of new things, of adventure, of breaking a comfortable and predictable routine. Look at his eyes.
We know the end of the story. He tries Green Eggs and Ham and loves them. His fear melts away.
Don’t let fear stop you from trying new things. You might like those Green Eggs and Ham after all.
