Well, often in such short stories, the main theme could be about human relationships. Maybe it's about the relationship between two men, perhaps a rivalry or a hidden connection.
The main theme is often about self - sacrifice and the different paths one can take in the pursuit of a spiritual or noble goal. Instead of following the other wise men to see the baby Jesus, the 'other' wise man is constantly distracted by those in need along his journey.
It could be about jealousy. In many stories involving multiple wives, jealousy often plays a big role as the other wife might feel left out or less favored.
The main theme could be about revenge or justice. In the story, the characters might be dealing with past wrongs and deciding how to respond.
The main theme is the significance of faith and perseverance. The other wise man in the story has faith that he must meet the Messiah. He perseveres through many years, facing hardships and distractions. His journey is not just a physical one but also a spiritual exploration, which shows that having faith and the will to keep going in the face of challenges is a central aspect of the story.
The main theme could be exploration. Since it's about a rocket man, it's likely that exploring outer space or new frontiers is a central idea.
The main theme might be about the relationship between the rent man and the tenant. It could show the power dynamics, the financial struggle of the tenant, and the impersonal nature of the rent - collecting business.

The main theme could be about strength and resilience. In many stories, a'man of iron' might represent someone who is unyielding in the face of difficulties.
It could also be about resourcefulness. The rag man makes use of what others discard. He might show how people can find value in things that are considered worthless by most. For example, he could be using the rags to create something useful or sell them for a small profit, which shows his ability to survive in difficult circumstances.
One possible main theme could be the struggle for freedom. Since the man is bound, his attempts to break free or come to terms with his restricted state might be central to the story.
