I’d also suggest that you make a “list” before you go to confession that way you don’t let things slip your mind. I used to be able to keep all those things in my head, however, recently I’ve started writing out a little outline before I go to confession that way I don’t forget when I get in there (scary that at 20 I’m forgetful, huh?) I like the list idea because you can have confidence going in and coming out of your confession that you remembered everything you wanted to. Yes, when you forget something in confession it is forgiven along with all of your other sins, however, I started realizing that I was “forgeting” too much and maybe I should put more time and effort into examining my conscience and preparing for confession.
