I’m from Scotland, and when I was a kid, it was assumed that everyone was Christian. It was extremely uncommon to be raised atheist - all of my friends have Christian parents, pretty much, and every school was a religious school. It wasn’t too hardcore or anything. We had lots of religious lessons in class, the school got together twice a week to pray, read bible stories and sing hymns, and we recited the Lord’s Prayer before lunch each day. I wasn't really interested in any of it but also I didn’t make a scene or ask to sit out or anything, and we were never forced to read from the bible or anything like that. I have read the bible, out of personal interest, but it was never expected from me.

High school was a bit similar but not as much - we had the school chaplain (priest who partnered with the school) show up once a fortnight (every 2 weeks) to deliver a sermon or religious lesson or whatever, and they were always good for a laugh. My favourite lesson of his was about how text speak (this was before smartphones, so we all typed on the 9-digit phone keypads stuff like “hey hru will u b going 2 skl 2mro” meaning “hey, how are you? Will you be going to school tomorrow?” was common) could be used with God as well - we could say “hf” to mean “Heavenly Father” and lol could mean “lots of love”. We got a kick out of that for a few weeks sending eachother ironic texts that we had meant to send to god but got the wrong number.

Wait, what was I talking about again?
