Goodbyes are a norm of life. Not all goodbyes are accompanied with smiles and merrily waved palms. If even one of two companions find happiness and meaning in their new journey, perhaps the bidding of farewell finds justification. In that case, it is left to the other fellow to sink or to swim, to find some meaning and walk forth, or to just perish. The ledgers are balanced otherwise. It is the nostalgic, lovelorn heart that fails to spot the error in their judgement.
We brace ourselves and march on to live another day. This forlorn companion suffers more in imagination than in reality.
