what kind of tree is that

someone asks you
what kind
of tree
that is in
your back yard.
shady, and thick,
healthy with
green, and you
say hmmm, not
knowing, but
start throwing
out all the names
of trees
that you do
know. birch,
a maple perhaps,
oak, or
pine, but you
know it's none
of those,
it's a different
kind of tree,
no, not even
a weeping willow,
you say, perplexed,
taking out
your phone camera,
murmuring hold on,
let me google
it.
