You need a little armor on when talking with a crazy person. His attack will not be predictable; He’s breaking rules of the social contract left and right. So you gotta get a little creative with your armor. Strap on an astro turf welcome mat, extra protection from one with a plastic flower. String some butter dishes together. Put a colander on your head. Pull on your rain boots. Wrap a measuring tape around your wrist. If you have a sandwich board handy, definitely get into that. Boxing gloves will help you. So will a clown nose. You might just have to don these in your mind but it will be worth it.
