A childhood belief about trains

One morning when I was four my father left to catch a train into the city for work. He returned a short time later because the trains were not operating that day. My mum then told me that there was a 'train strike'. This was the first time that I heard the word stike (where you stop work to protest for higher pay and or better conditions), I actually thougth of the word 'stripe'. Being very young I had no idea what a strike was so I pictured all of the trains in the city being covered in black stripes (such as being tagged with graffiti) and infested with nasty black vines which made them unsafe for taking passengers during the strike.
