I expect most of us were brought up to believe there was only one god.
It occurred to me that there could well have been two. They couldn't agree about which one would create the animal kingdom so they settled on a compromise, to have male and female.
My parents were atheists. I still got sent to Sunday school. It took me a very long time to realise why they were so tired on Sundays that they had to go to bed in the afternoon.
Not that I went to Sunday school. Me and a mate used to pool our collection money and buy 5 Woodbine.
