Well, I'm no longer Catholic, but it's true you can't really scrub the Catholic out of the girl very easily if she was taught by nuns for 12 years the way I was. They weren't sneaky. They were pretty bold, actually.
The nuns and the priests I dealt with were strict and unpleasant, for the most part. But my questions annoyed them -- and probably to this day!
I remember taking classes every Sunday to learn about religion. They were called CCD. Did you have to take that?
