My mom once told me that on one of my old elementary schools or kindergartens there was a model lighthouse in the teachers room (because the school was called "the lighthouse"), and I had somehow gotten myself an exemption from the globally written no-students-in-the-teachers-room law to turn on the little lighthouse every morning.
The first thing I would do every morning when arriving at school was exactly that. Run straight for the teachers room, turn the lighthouse on, and then run to class.
That was my job. My responsibility.
She even told me that she was there one day when the teachers were having a meeting with some folks from the municipality board who were unsuprisingly quite surprised by this random lad just charging in and flicking a switch on this model lighthouse before running away again. And that the teachers just said something amongst the lines of "Nah, it's okay, he's the lighthouse-keeper here".
I also remember that as a kid I had developed some sort of procedure for going to the toilet at night where I would turn on and off the lights in such an order I wouldn't have to walk in the dark (which was desireable for obvious kids reasons)
If I recalled correctly, I would turn on my bedlamp, then turn on my room light to turn my bedlight off again, turn on the light in the hallway, then run back to turn off my bedlamp, then run downstairs to turn the light on there, run back up to turn the hallway light off, and then go downstairs to take a leak before doing the same procedure in reverse to get back in bed.
