Yes, I think children do keep their promises. They're often taught by their parents and teachers about the importance of honesty and being trustworthy. When they keep a promise, they might feel proud and responsible, which is a good feeling for them. Plus, they often want to gain approval from adults, so they try to stick to their word.
はい、私は子供たちが約束を守ると思います。彼らはしばしば親や教師から正直さや信頼性の重要性について教えられます。約束を守ると、彼らは誇りや責任を感じることがあり、それは彼らにとって良い感情です。また、彼らは大人からの承認を得たいと思うことが多いので、約束を守ろうとします。
