It's been a long time since I felt guilty for missing a meeting. I think it was about the time that I realized that I hadn't learned anything new or enlightening that wasn't arbitrary "new light" at the meetings since my teens. Since I have a pretty good memory, I didn't feel the need to go and have stuff repeated to me ad nauseum.
Since learning TTATT, it's gone from being something of a relief the days that I miss to being either a greatly joyous or very frustrating occasion on the days that I miss meetings. Joyous when my wife stays home with me, frustrating otherwise.
