Blind Blessings

At the end of the tunnel, There's always a light, Sometimes soft, At other times bright... But the length of the tunnel, Determines your relief, Expecting to see it, A foolish belief... Nothing is certain, As seen by the night, For the sun does set, A suppression of light... "Clear as day", A reference to how we "see", But clarity is fickle, And may not always be... So acknowledge the sun, For a new day is born... If taken for granted, Forever shall you mourn.
