The perfect metaphor doesn't exi-- oh wait, it does. Linked lists are literally just shady middlemen of data structures, connecting you to the next node like some back-alley information broker. "You want the next value? I don't have it myself, but I know a guy who knows a guy ." And that's how you traverse the entire criminal organization of nodes until you finally reach null, the equivalent of "sorry pal, end of the line." No random access here - just an elaborate chain of referrals that would make even mob bosses proud.
