I think my first substitute activity for Catholic mass was hand ball, on Sunday morning. My mom thought I was going to church- I wasn't up to all of the confrontation about my beliefs yet.
The time I spent on the hand ball court allowed me to stop the dogma from filling my ears. This was pure relief! This was the time where my own thoughts could surface in my mind's eye. This time to myself allowed the cookie cutter of Roman Catholic life and times to break down. I stopped feeding that software with my potential and was freed from it's subroutines and paramiters.
