What is the exposition of the wind in the willows

When the novel begins, Mole is at home doing spring cleaning, and he is quite bored with it. He casts down his cleaning instruments and runs to the surface to plow through rabbits along the roads and through grasses in the meadows to the river. It is at the river that Mole meets Rat, and the two form an immediate friendship. This friendship brings Rat’s friends Badger, Otter, and Toad into the story.
