I disagree with the WAS script. I believe it is a spouse being able to vocalize their frustration and resentment. It is healing for them to get it out. The LBS can't take it personally and doesn't need to buy into their reality. Two people witness the exact same incident and have different recollection. That's why police interview all the witnesses. It's life. The LBS needs to use an imaginary umbrella, and very thick raincoat & let the WAS emotionally throw up & get it out into the open. Then and only then, can the two people begin to communicate without the buried anger and resentment.
