call me a romantic by my grandparents are a testament of this saying.
My grandfather was madly in love with a girl when he was younger but he was arranged to a marriage by his family and was forced to marry another woman.
Fast forward 50 years later when he was 76, his wife passed away and he met his previous girlfriend again (yes after 50 years). Apparently the girl did not marry because he was in love with my grandfather even after 50 years. They got married 2 years later and if this isn't the clearest real life example of destiny, I doubt anyone can give a better story
