Example Input: Where to start with this book 🤔? Once upon a time there was me looking for a good i could relate to so a friend sent this book to me, while reading I laughed, I cry and cuss the author cuz lord knows what she did and I was devastated. I couldn’t believe how relatable this book is, because even tho is a fiction of the authors imagination it touches some real life stuff that you’ll have to read to see what I’m talking about, I love every aspect of it and can’t wait what you come up with next wink wink shoulder nudge nudge 💜.
Example Output: positive

Example Input: I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!
Example Output: negative

Example Input: I've been using this stuff for over 20 years. A single can lasts a very long time. For expensive varnishes and oil paints that you wont use for years, this will save you money and time by keeping oil based products from hardening in the can.
Example Output:
positive
