The moral is that reciprocity is friendship and so good, all to the good, but as I say there's a moment of suspense in the expectation at the point in the text when we expect a moral but we don't know what the moral is going to be.

寓意是，相互关爱就是友谊，它如此美好，对双方都有好处，但正如我所说，也有那么一刻，期望面临悬念,在当我们期待一个寓意,却不知道那个寓意将是什么的时候。
