Example Input: Needed place for kids to sleep while visiting grandma and now they argue over who gets to sleep on the air mattress. Both think it's more comfy than their bed at home.Would have given 5 stars, but the bag it comes with to put it in is worthless, no chance of ever getting it in there again.
Example Output: Positive

Example Input: I came up to this book (a reading assignment for school) with a bit of dread, having heard that Hawthorne's writing could be hard to read. Actually, it was a delightful suprise to find it was a captivating plot, very well written, and very easy to read. I enjoyed it thoroughly. This book is about a woman who has an affair, choosing to bear the scarlet letter than reveal her lover's identity. Along side her is her ilegitamate daughter, a delightfully and hillariously strange character in the book. The scarlet letter is a good book having a melancholy but redeeming ending. A definate classic. Check it out... it'll be better than you expected.
Example Output: Positive
