The child asks
Daddy, what is a tree?
Outside he points and says

That__ is a tree.

Casting glance from elm to conifer
what's that
Why that's a tree as well dear child

but they don't seem too much alike
so please, Daddy,
What is a tree?

now that's a lot like poetry
for poems can take most any form

but meter metaphor and rhyme
with many sly techniques sublime

define a poem as
well...poetry

Now that's not very illuminating so please I plead

what is poetry?

an instance in Time?
a moment in Space?

the vision snared with scratch of pen?

might just as well ask
what is?...a tree
