Why do people miss things before they are even gone?
Some memories begin before the moment ends.
The trip is not over.\n\nThe child has not grown up.\n\nStill, sadness appears.\n\nThe hidden mechanism is future nostalgia.\n\nHumans imagine endings before they arrive.\n\nAwareness increases appreciation.\n\nBut appreciation sometimes arrives carrying grief.\n\nPeople think nostalgia belongs to the past.\n\nVery often, it begins in the present.
