Sunshine

"There's little sunshine in my heart,
  A Slack to spring, lead to sink:
There's little sunshine in the world,
            I think."

"There's glow of sunshine in my heart
  (Cool wind, cool the glow):
There's flood of sunshine in the world,
            I know."

Now if of these one spoke the truth,
  One spoke more or less:
But which was which I will not tell:
            You guess.
