Input: Consider Input: I was expecting to read a book about the Amish. What I read instead was a very self centered book about a woman searching, rather blindly, I felt, for herself.She had very little in the way of insight into Amish life, even after spending a period of time with them. And her inability to get outside of her own head/her own life was not terribly interesting to read.For someone who always longed to be a 'star,' I am sure publishing a book was quite a thrill for her. Shame she used the Amish as a platform for her own ego.

Output: Negative

Input: Consider Input: Can not beat this item for the price, hands down!Excellent product with all the features you could want, period.

Output: Positive

Input: Consider Input: This junk really stinks (literally, it smells horrible)!! I've used better products and those other attractants did trigger responses in females. I've been INSULTED by the females at my job after using alter ego and been told things like "what in the world is that new cologne you're wearing, it doesn't smell good". I told my wife I was wearing a new type of "after shave" and she hates it so much I had to promise NOT to wear it to bed. Don't believe the hype of Alter Ego, there are far far far better Pheromones. It's apparent they tried to give it a MASCULINE tone, but they went too far.
Output: Negative
