A client of mine came up with this idea that they now use, after I had gotten on to her about the "I'm sorry". Now she replaces it with "I'm thankful". I'm thankful for the extra appointment, I'm thankful to be with you X months later, I'm thankful for being able to text, I'm thankful you allow me to talk about yucky feleings... etc. It was a pretty neat idea and worked well!
