If you’re anything like me, you spend about 87 percent of your mental life winning imaginary arguments that are never actually going to take place. You makeup little stories to explain misunderstandings and conflicts, starring yourself as innocent victim and casting your antag-onist as a villain driven by sheer, unilateral, motiveless malice. If you’ve ever made the mistake of committing your half of these arguments to print or email, you probably learned, as I have, that the other person’s half of the argument fails toc onform to the script you wrote for them.
