From that point, and for most of my adult life, my atheism was no big deal. It was a part of who I was, but I didn't go out of my way to talk about it.
Sounds familiar. I did that in 1975. In 2009 I still had not been very open about. I had to interact with suburban parents who are 90% church going. My kids are in college now, so no more pretending to be sitting on the fence about religion.
