No Rival Like The Past

As those who eat a Luscious Fruit, sunbaked,
Full of sweet juice, with zest, until they find
It finished, and their appetite unslaked,
And so return and eat the pared-off rind; -

We, who in Youth, set white and careless teeth
In the Ripe Fruits of Pleasure while they last,
Later, creep back to gnaw the cast-off sheath,
And find there is no Rival like the Past.
