Obviously, the old man is one of the main characters. He is likely the one who the story revolves around and has interactions with the magic bowl.
If there are other characters in the story, for example, people in the old man's village or a wizard who gave the old man the magic bowl. But without more details, we can be sure that at least the old man and the magic bowl are central to the story.
The magic bowl can also be considered a main character in a sense. It has its own special properties, like magic powers, which drive the plot. Without the magic bowl, there would be no story as it is the source of the extraordinary events that happen to the old man. So it plays a very important role, almost like a character with its own kind of 'personality' through its magical abilities.
The moral might be about the importance of using power or magic (from the magic bowl) responsibly. Maybe the old man has to make choices regarding how to use the magic of the bowl, and if he misuses it, bad things happen. So it teaches us to be responsible with any special abilities or resources we have. For example, if the magic bowl can produce food endlessly but the old man starts to waste it or use it to manipulate others, he will face consequences. This reflects on our own lives where we should use our skills, wealth or influence in a proper and ethical way.
The main characters are, as the title implies, the old man and the old moon.
Well, the moral can be seen as a warning against ageism. The family in the 'old man and wooden bowl story' fails to value the old man. When the little boy imitates their behavior towards the old man by making a wooden bowl for them, it hits them hard. It basically tells us that we should not neglect or mistreat the elderly just because they are old, but instead show them love and respect.
The moral is probably about the importance of taking care of the elderly. The family's mistreatment of the old man because of his inability is wrong, and it shows that society should respect and care for the aged.
The main characters are an old man and a young man. The story usually revolves around their relationship, their conversations, or the events that happen between them.
The main characters are Santiago, an old and wise fisherman. He has a lot of experience and knowledge of the sea. Manolin, a young boy who looks up to Santiago. He provides some emotional support to the old man. And the marlin, which is not a human character but plays a crucial role in the story as it is the object of Santiago's pursuit and the source of his great struggle at sea.
The main characters are the old man and the donkey. The whole story revolves around the old man's actions and decisions regarding the donkey and how others react to them.
The main characters are the old man and the king, of course.
There might also be other characters like the people in his village. They could be the ones who seek the old man's advice or the ones who are amazed by his cleverness. For example, the young villagers who are facing some challenges and come to the old man for help. Or perhaps there are some antagonists, like the thieves who try to outwit the old man but end up being outsmarted by him.
The main characters are, as the title suggests, the old man and the goat.
