Influencing Factors Interpretation
A pile of sociological evidence suggests that the enduring "Friends" reunion is less a matter of Ross and Rachel's cosmic destiny and more a precarious math problem, where the sum of your post-high school life—be it an urban move, a divorce at home, or simply not having AP Bio together anymore—relentlessly subtracts from your friend tally unless you strategically add in things like shared extracurriculars, digital check-ins, or the sheer dumb luck of staying in the same socioeconomic lane.
