One thing I think about sometimes, but definitely don't talk about eg on Twitter, is the weird latent feelings I have for churches and religious sites despite being sort of officially atheist since my mid-teens. I visit cathedrals on vacations. Something in my brain still connects with this even though I rejected God and Christian teachings more than twenty five years ago. It's especially weird because I wasn't baptized until I was seven or eight - my mother converted I guess in her mid 30s. We came to it relatively late.
Years ago I thought this would pass, but it hasn't. I'm still firmly a non-believer but I find it fascinating how something like this lingers, embedded somewhere in the brain's darker regions.
