The last time I read Wind in the Willows, I was about 14 years old. I recall being slightly put off. Something seemed just... off about the story.
Having re-read it, I now know what bothered me. This book really isn't for kids at all. It's mature--not "mature" in a "bad" sense, but mature in the way it looks at the world. Characters have experiences that I think only an adult would completely comprehend--such as Rat's sudden wanderlust. Additionally, I think I was trying to find a point to it, but there's really no such thing. There's a light overarching story arc revolving around Toad's motorcar shenanigans, but that's as close as it gets. Most of the time it's a meandering series of short stories about animals farting around in a forest.
But what a fun fart-about it is! It is spectacularly well written--I am in awe of Grahame's prose--and includes lovable characters, great dialogue, and hilarious asides. The human mannerisms of the animals are charming, and it's quite funny to think of them as proper English gentlemen. The icing on the cake is Grahame's loving descriptions of nature and all the life that lives in it.
So many elements make this story precious and unique. It stands the test of time with ease. Please give it a chance! I think you'll really enjoy it!
