and this, my singular obsession

I once shook hands with happiness
some night so late
it was early.
I didn't get a glimpse of
his eyes,
so quickly did he go...
for some reason, though, I tend to think
they were a shade
of emerald green.
His grasp was strong
like the tide
except not driven by any moon.
And when I asked him for the time
he said only
that he didn't have one.
Perplexed
I thanked him anyway
and he tipped his hat to me
and off he went.
