Decisions are hard.
And while you’ve got pens to help you through the difficult personal choices, when there’s another person involved, it can be difficult to back down without losing face. That is, unless you brought a few wood-grained decision wafers.
They’re called “tiebreakers,” and they help you choose between the big choices like “I Apologize”/”You Apologize” or “I Will Do It”/“You Will Do It.” The trick is that in most cases it doesn’t really matter who comes out on top—so appealing to the flipped coin can help you settle the matter without either party feeling exploited.
At least until you start weighting the coins.
