Human beings encounter a great many things during the course of a lifetime. Whether it be other people, film, music, literature or simply day-to-day events human beings build up a vast catalogue of experiences. Sometimes these experiences collide and seeing one thing will inevitably bring up the other thing.
For me, this is most intense when seeing a freight train rollin on down the rails. In an instant my mind flashes to Jack Kerouac and On the Road. For the two minutes that train rumbles down the line my mind travels back to America circa 1957 and gone are the rules and regulations of today. In that small time frame you can just visualize yourself hopping on a carriage like Jack and going were the train goes, reveling in the new-found freedom you have just attained.
Then the train passes, Kerouac fades to black, and you return to normality. But while the train is there, there is an undeniable urge to go on the road.
I am actually quite happy with this, although the first paragraph is really bugging me. It just feels clunky and ever so slightly unwieldy. It is also a little cliché.
