Okay, imagine there's a story called "Beauty and the Beast". In this story, there's a scary beast who lives in a castle. But over time, a beautiful girl named Beauty comes to the castle and starts to get to know the Beast. As she spends more time with him, she begins to see that he has a kind heart and is actually not as scary as she thought.
Now, the thing about "Beauty and the Beast" is that it shows us that sometimes, what's on the outside isn't as important as what's on the inside. Even though the Beast might look scary and not very attractive, he has a good heart and that's what makes him beautiful.
So, the moral of the story is that we shouldn't judge someone or something based only on their appearance. Sometimes, the things that are really important, like being kind and thoughtful, are things that we can't see just by looking at someone.
