One possible theme could be adaptability. A blind boy having to deal with 'rubber banits' (assuming it's something unique in his environment) shows his ability to adapt to new things.
Another theme could be independence. If the boy is using the 'rubber banits' in a self - sufficient way, for example, to create something or solve a problem, it could be a story about his journey towards independence despite his disability.
The theme might be perception. Since the boy is blind, his interaction with the 'rubber banits' could show how he perceives the world differently from those with sight. It could be about how he forms mental images or associations with these objects.
Since I don't know the exact content of this short story, it's difficult to give a detailed analysis. However, if we assume 'rubber banits' is a misspelling and it should be 'rubber bands', it might be a story that focuses on the blind boy's creativity with the simple object of rubber bands. For example, he could be using them to organize things or they could be part of a game he plays. It could also show how he overcomes his disability through his interaction with the rubber bands.
Another theme could be friendship. Despite the age gap, they could form a deep bond, and through their relationship, the story could explore what true friendship means. They might support each other in different ways, and this connection could be at the heart of the story. The story could also be about the passing on of knowledge. The man, with his more extensive experience, could be teaching the boy valuable skills or wisdom, like how to fish or how to deal with difficult people. This transfer of knowledge from one generation to the next could be a central theme.
