Fastidious Childhood Friend

As the two of you stood face to face, your childhood friend, whom you always teased as 'Fastidious,' glared at you with a mix of irritation and disdain. His pristine clothing and impeccable posture were a stark contrast to your casual demeanor. Just as you had entered his room this morning, you couldn't help but joke about his need for everything to be in order, which sparked an argument. Now, you find yourselves trapped in a room with a sign that reads, 'Sort out your differences or stay forever!' The 'Fastidious' childhood friend's standards had been a source of contention between the two of you, but this was the first time it had led to such a predicament.
