Example Input: I have a sixteen-year-old who is questioning all morals. I was finding it difficult to put into words the importance of morals. I bought this book for her to read. She isn't reading it, but I am and I'm finding it very helpful in facilitating discussions with her. At dinner time I bring up one of the seven moral virtues and ideas that the book presents. I've found that it leads to great conversations with her about character and moral behaviors. It has given me the words for concepts that can be difficult to convey in our current morally challenging times. I recommend buying this book when your children are young and referencing it often.
Example Output: Positive

Example Input: This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
Example Output: Negative

Example Input: I bought the pillow covers and the mattress covers and they are great. They wash and dry well and do exactly the job they should.....protecting pillows and mattresses.
Example Output:
Positive
