Answer:
<em>The Adventures of Huckleberry</em> <em>Finn</em> is Mark Twain's novel, a sequel to <em>The Adventures of Tom Sawyer. </em>The novel is about a young boy, Huck, and his search for freedom and justice. Huck joins Jim, a runaway slave, and the two of them travel down the Mississippi river.
In this particular excerpt, Jim explains that Huck is going to have both happy and sad moments in his life. This is how life works, and the sooner Huck accepts it, the better. Jim argues that Huck is going to get hurt at certain point. Sometimes, he will not feel well, but will eventually get well again. Jim, therefore, suggests that not everything turns out how we planned, but this is something we must accept. After a period of darkness, there is a period of light - happiness is temporary, just like sadness. Our aim is to enjoy life despite all the troubles.
