The Three Faces of Diagonals

Earlier today
the trees, still
in winter,
shot out a strong
diagonal shadow,
traversing the
sleeping leaves,
and only halted
by another tree in
their path.

Then in the late
afternoon most of
the shadows disappeared,
and those that remained
had a soft edge and
not much contrast with
the ground.

Now, at sunset, the
trees are enjoying
the multicolor sky
as they remember
a good day for
productive shadow
making.
