The world is full of all kinds of people, but in some ways, it’s easiest to divide us into two specific groups: those who think toilet paper should come over the top of the roll, and those who think it should come under the roll. Or those who drink coffee and those who drink tea. Or morning people and night owls. Based on the 2 Kinds of People Tumblr, this interactive game book is the perfect conversation starter and ice breaker with 84 pairs of clever illustrations designed to prove there really are just two kinds of people in this world. Categories include food, technology, home, and daily habits, and range from inconsequential preferences to absolute deal breakers. Here’s how it works: two people page through the book together. Each person decides which of two opposite illustrations best describes his or her personality. If they choose the same one, it’s a match! The plastic scoring wheel in the back of the book allows them to keep track of their number of matches. When finished, they see where their match number falls on the Scale of Compatibility, also in the back, to determine if they’re a good pair (or are at least suitable companions for a cup of coffee). Everyone loves a personality quiz—particularly one full of opportunities for good-natured disagreement.
