There is a heated fight and your girlfriend is crying, and you are crying, too. Things were said in anger to each other but broken hearts can sometimes never be mended. You kiss one final time and part ways. It is for the best, you tell yourself. A knock at the door, but who could it be? You open the door, already knowing the answer in your soul. It is the folder icon. You hold each other, heart beating against heart. You are destined to be together. This is an eternal love.
