By any normally accepted standard
three words are scarcely sufficient
to be considered a poem.
The Japanese, who have a gift for conciseness,
might be sympathetic.
(Haiku, after all,
    at seventeen syllables,
       are pretty compact.)
But three words! It's not so much concise as,
to put it bluntly, short.
If I say that, when I try to write a poem for you,
"I love you" is all I can think of,
that is no excuse.
And the fact that my meaning is new and unique
(for me and for you)
makes no difference either.
If only there were some way out of my difficulty.
I love you, I love you, I love you.
There, that's nine words.
Will that do?
