Unless you live in the American South. I moved to Alabama recently and have discovered that people talk about praying/God/miracles/signs all the time. It seems like everyone has a story similar to the ones you mentioned. Casual friends have pulled me aside deeply concerned by my lack of spirituality as I generally don’t talk about religion/spirituality/faith/miracles/signs in non-spiritual settings like, say, art class. Art class then became a three hour spirituality lecture. It was awkward. I try but I still find it really difficult to discuss spirituality with anyone that I’m not close friends or family with. I do try now though, in the hopes of avoiding further incidents. It doesn’t help that I’m chronically ill so people always ask to pray for me and ask me why I don’t ask them to pray for me. Culture thing again, I think. It just would never occur to me to ask someone for prayers.
As for sex, I generally don’t think or talk about sex unless someone else does first. People don’t actually think about sex very often, right?
