...to keeping your peace in a situation where you don't care to enlighten the person you're mad at is that you are now prone to a ton of passive-aggressive bullshit. Rather than confront the situation, the true passive-aggressive will pussy-foot around the problem. They will make oblique remarks to mutual friends in the hopes that they will get someone to ask them what the problem is. Then they hope for allegiance from those people.
Know what? I am halfway enjoying all of it. Why? Because I know I'm right.
