If you are of a certain age and experience, you already know about Dharma Bums.If you are of another certain age and experience, this book goes against everything taught by Saint Ronald Reagan, and so you should avoid it.If you are young, give this book a try. Better yet, instead of buying it, go to the local library to read it. Unless the people I described in my second paragraph have taken over and there are only Approved Books in the library...if there are libraries at all. Libraries cost money, and that means (shudder) taxes.For everyone else: this is Kerouak's best work.

Ex Output:
Positive

What a great album!!! I never knew she sang as well. I have seen her in French movies and enjoyed greatly her acting in those movies. Now I even adore her more, because not only can she act, but she can sing as well!!!Go Charlotte Go!!!! Can't wait for her next album.

Ex Output:
Positive

Why do books such as this keep being required reading in high schools? Havent there been any authors in more recent time that would provide students more relevancy? Obviously this appeals to those who are truly literature lovers--and that's fantastic. But for most kids, give them something they'll enjoy reading and maybe they'll learn to love literature more. Books like this just antagonize and demoralize those who are not naturally literature lovers.

Ex Output:
Negative
