Mom was a pretty strict Catholic. I went to Catholic school until high school. We were really active in the church. I was an altar boy (her decision, not mine). I don't remember ever really believing in it, except for all the bad stuff, of course (hell is scary!). I probably would have kept going through the motions to keep her happy, but when she died halfway through 8th grade, I was done. My dad was more or less agnostic, so he didn't make me go after that.
I remember reconnecting with some of my middle school friends a decade later, and was surprised to find out that they were mostly still pretty devout. A couple of them are priests now.
