If only you could really turn around to look back you'd realize millions of people that never saw you and you wouldn't turn around again. You have to look ahead to see a face you recognise, and don't look back. What's left behind stopped to recognise you, what is left behind didn't want to see you enough.
After life has slapped you profusely you must get used again to a more delicate touch.
Finding someone for whom its worth seeing it through is just complicated nowadays. You don't leave your heart on a falling star.
It's useless to illude oneself, once you've lost the moment nothing is the same, people return but things don't go back to being what they were, people come back but you can't go back to restart from a moment that has vanished in time.
