The book Flying at Night is a prequel to The Little Prince. It is as excellent as the little prince, which makes me understand the deeper mystery of the little prince. I like it very much.

I like one of the characters very much. His name is Riviere. He is the manager of an airline in Africa. He has a heavy responsibility. On a night that should have been happy, he had the desire to talk, so he found the engineer Le Hu, who, like him, shouldered a very important responsibility. Riviere remembered his first love. He didn't love well. So he asked Le Hu, "Have you ever been in love?" Le Hu's answer was within his expectation, and Le Hu said nonsense. That's what he did. Yes, that's it, Riviere thought.

I think their so-called "just like that" may be an ungrateful hope for life, or an indifferent attitude towards everything.

The reason why I think so is because I saw a description in the book Nocturnal Walking:

Before the plane arrives safely, it will never be a victory, nor will it end a war, thus opening an era of happiness and peace. For him, any step is always just a step, and there are still thousands of steps to go.

Perhaps this passage is telling us: Don't be too happy before the answer is decided, and don't be proud of winning an award or finishing something. This is only a small part, and there are still many things to do in the future.
