For however many kumquats that I eat
I'm not sure if it's flesh or rind that's sweet,
and being a man of doubt at life's mid-way
I'd offer Keats some kumquats and I'd say:
"You'll find that one part's sweet and one part's tart:
say where the sweetness or the sourness start."
I find I can't, as if one couldn't say
exactly where the night became the day,
which makes for me the kumquat taken whole
best fruit, and metaphor, to fit the soul
of one in Florida at 42 with Keats
crunching kumquats, thinking, as he eats
the flesh, the juice, the pith, the pips, the peel,
that this is how a full life ought to feel,
its perishable relish prick the tongue,
when the man who savours life 's no longer young,
the fruits that were his futures far behind.
Then it's the kumquat fruit expresses best
how days have darkness round them like a rind,
life has a skin of death that keeps its zest.
