The biggest thing I’d be worried about is, if I had to write stuff down to remember to say it— then that sort of implies I didn’t really contemplate my shortcomings seriously in the first place, if that makes sense?
So, for example, if I was impatient with my kids, self-centered in my actions, and wasteful with my time, those are things that are on my radar, and I notice them when I do them, and I try hard to improve myself to be a better parent, be a more responsible and generous adult, and generally be closer to the person that God made me to be. But if I have to look at a list to remind myself that I was impatient with my kids, self-centered in my actions, and wasteful with my time— then that kind of implies it doesn’t really bother me that much that I’m being impatient/self-centered/wasteful, because I wouldn’t remember that I had erred in such a way if I didn’t have a list to remind myself of that.
Our Reconciliation class was taught to say at the end-- “For these and all of my sins, I am heartily sorry” to cover the stuff that we accidentally forgot, or perhaps never noticed in the first place.
