Example Input: My little boy is just getting interested in these blocks. They are too cute! He's learning to manipulate the block in his hands. The little things inside the blocks are adorable. Some spin, some twirl, some rock. A definate upgrade from the standard wooden blocks.
Example Output: Positive

Example Input: 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.
Example Output: Positive

Example Input: I love this blouse! It's nicely cut and quality material. Unfortunately for me I ordered the wrong size and mine isn't available so I have to return it. I'm usually very disappointed in quality when I order clothing online, but risked it and took another chance. I was happily pleased! Plus this is made in the USA, which is very hard to find. I received a little National catalog with the blouse, that I plan to use. Just sad I can't keep this beautiful red blouse...
