How would you compare and contrast Sam and Curtis in the novel Seedfolks by Paul Fleischman?

Sam is a seventy-eight year old Jewish man who spends his life promoting peace and attempting to bring different individuals together. Since Sam is too old to work in the garden, he hires and pays a Puerto Rican boy to do the work. Curtis is twenty-eight years old and is known throughout the community for his massive muscles. Curtis begins planting tomatoes to show his ex-girlfriend, Lateesha, that he still has feelings for her. After noticing that some people have been stealing his tomatoes, Curtis gives a homeless teenager named Royce the job of protecting his plants in exchange for some food and a sofa to sleep on. Although Sam is much older than Curtis and they do not share the same race or reasons for working in the community garden, both characters are caring, sensitive individuals. Both characters also help other people in the community by giving them jobs. Similar to how Sam pays the Puerto Rican boy to work in the garden, Curtis gives Royce the job of protecting his plants.
