When I was a young boy in the 90s, I was in the Cubs, I decided later that I didn't want to stay on into the scouts but that is another story. To cut a long story short, I'm not a people person so I should never be in social clubs.
One day we were taken camping, we slept in tents. There was communal toilets in the next field. At night when we needed to go to the toilet, we would get our torches out and navigate our way in the dark to the toilets. I really enjoyed doing that because the torch light was just bright enough to let me see where I am. In that place it was very dark at night, everywhere was pitch black. It is nice to walk around in a dark field with just a torch to guide you. It is hard to explain how joy can come from such a thing but it did.
I'm guessing that it is the simplicity of the darkness and the effect of the torch light on the ground that made it a joy for me.
My torch had a lense on it so it would slightly shimmer the light in the middle away from white and into the different colours when it wasn't level.
