A childhood belief about cars

When i was little i was convinced that the street lights with two heads, like you get on motorways (in the UK) or on busy roads, were alive and could show their emotions. If both the heads were lit then the light was happy, if they were both unlit than it was sad, and if only one of the two was lit then it was happysad.whan my dad was driving down the road i would play a game with my mom to see how many i spotted and would have to say what the lights were feeling out loud as we passed each one. One time time all the lights on the motorway were only half lit and i went a bit mad just continually saying happysad(they are very close together so you can imagine how fast i had to say it).another time there was a power cut... I thought the world was coming to an end and thats why all the lights were sad and i burst out crying
