Casy looked down into Grampa’s eyes and they were clear and deep and penetrating, and there was a knowing serene look in them.
– John Steinbeck
The Grapes of Wrath, Chapter 13. When Grampa dies, there is a serenity in his death. Having nothing to live for when taken away from his family home and farm in Oklahoma, he is more at peace in death than in life as a migrant.
