I don't go to church. I'm not religious either. With the exception of a few months senior year of high school and the occasional holiday, I haven't attended a religious ceremony that wasn't a wedding or baptism of my own free will either. But I live in the bible belt and there's some sort of church/temple/synagogue/parish/mosque/something everywhere you look. I pass at least one each way I leave my neighborhood. So a lot of non religious affiliated events happen at these places of worship simply because it's a space that can host an event.
So one Sunday morning I'm running an errand and notice the church parking lot is full as I drove past. I think to myself:
Huh, wonder what's going on at the church?
