You'll never even catch me doing that 'soft atheist' thing of very softly singing along or just mouthing the words, looking down at a hymn sheet every few seconds to check the words. To state the obvious, as an atheist, the hymn sheet is no use to me. So I just stand there, looking straight ahead or up at the ceiling, and do nothing.
I remembered being young in the late '70s and early '80s and growing up at the height of the Cold War. I remembered how scared I was of nuclear weapons, how often I though about them and about the possibility of everything and everyone I knew vanishing in a second in temperatures hotter than the centre of the sun.
