Unreciprocal love is the type you give to someone who cannot at that point in time, pay you back!
It is the type given without expecting it repaid via the same route.
It is like throwing bread crumbs into the sea and watching the waves carry them deep into the centre of the sea, until it vanishes from your eyes. At a point, you no longer see the bread crumb for it has gone with the winds.
But is your bread crumb lost forever?
No.
For what we give, even when we don't expect anything in return, always comes back to us, multiple folds.
