trains are massive and when set in motion they have a
large amount of momentum but when theres another train
an older train , a heavier train , a train that is sitting on solid ground and has little momentum sitting on the same track yet pointed in the opposite direction and the two are brought together ... the train with the most momentum , the faster moving train , the shinny new train with all of its mirrors and illusions and magic tricks that was seemingly built by some clever magician rather than by a train builder that carries many more gullible people , people who more resemble some sort of circus troop or actors in a play that focuses on fantasy than all of the sensible people on the older train tries to go around the older heavier train standing firmly on solid ground but just cant because there isn't enough room to pass without colliding.
