Zombie movies are all the rage now, apparently (never been my thing). A zombie is dead, but won’t stop following you. If it catches you, it will hurt or destroy you, infecting you with whatever it is that made it a zombie. Finally, zombies have a bad habit of coming in packs that multiply rapidly.
In an argument, a zombie is a past argument that should be dead, but just won’t stop following you. Argument zombies can hurt or destroy your marriage, and they will infect your current argument. Once you have a couple of argument zombies, you can count on the number growing. If you both bring zombies into your arguments, the odds of being overwhelmed are great.
You deal with zombies one at a time, and you deal with them until they are really dead. Then, and only then, do you move on.
If your arguments have a way of becoming zombie infested, have a strategy meeting with your bride. Agree that zombies are never helpful, and should be put out of your lives. Do whatever it takes to deal with the past issues – fight each one until it’s dead. Then if either of you tries to bring up something that is settled, the other can counter with something subtle like screaming “Zombie!” at the top of his or her lungs.
