I asked my dad one day how the traffic lights worked. He told me that there was a department in city hall where a large group of civil servants was employed with pushing the buttons for green, orange, and red.
I then asked him why the lights would flash orange after 20:00 (as they used to do in my country) and in the weekends, to which the answer was of course that that was the civil servant would be done working.
I don't know if I actually believed this, but it made an uncanny kind of sense!
