The conversation between the children and the mathematical master means that children's dreams cannot be hindered by adults, even if they are frowned upon.
Explanation:
In this conversation, the children claim that they saw the happy prince who never thinks about crying for any reason. The mathematical master is intrigued and asks how the children saw this prince and they answer that they saw him in their dreams. The mathematical master disapproves of this, because he does not admit that children dream, but it is inevitable, because their dreams are unstoppable even if they are disapproved.
