What is the reason why I like my sister's poem red rain boots?

The content is full of childlike interest. My sister's red rain boots are a life poem in the second grade Chinese textbook of primary school. The author describes it from the perspective of children, which increases their nature of laughing and having fun on rainy days. I like it because the content is full of childlike interest and makes people yearn for it. The reason is the condition that leads to a certain result or another thing.
