I suggested that they add to the lists things they noticed in the weeks ahead. I also suggested that twice a week, they select one positive trait and express verbal appreciation for it to the spouse. I gave one further guideline. I told Betty Jo that if Bill happened to give her a compliment, she was not to give him a compliment at the same time but rather, she should simply receive it and say, “Thank you for saying that.” I told Bill the same thing. I encouraged them to do that every week for two months, and if they found it helpful, they could continue. If the experiment did not help the emotional climate of the marriage, then they could write it off as another failed attempt.
