Can you please paraphrase this for me:
Perhaps the most important theme is the one that Steinbeck introduces in the introduction and further spells out in chapter two: things and people are not always what they seem.
Steinbeck creates characters who care about each other far more than they care about a steady job or material possessions. In spite of their poverty, lack of social graces, and outcast status, they attempt to help each other. Although their plans are frequently ill-conceived and poorly executed, their actions come from the heart, creating both the warmth and pathos of the story.
