Which sea denies the pull of the moon?

What puppet dances to its own tune?

A barbed and chastening valentine

No choice at all; the fault’s all mine

Could do better, the report card says

But how to change one’s errant ways?

Alas, some choices can’t be mended

Outcome’s not as was intended.

Each act’s curtain draws to a close

Why it matters, none other knows
