Vertex

 
So it was like this:
He passed and she didn't see him!
It was so:
She did not see.
He passed.
The cars stopped
for him to pass
and she did not see.

He has a name
that she didn't hear.
So it was like this:
She didn't see his eyes,
lost when he passed
and he, not knowing
whether he was seen,
passed on.

They passed each other.
They didn't see each other.
Perhaps his voice in the wind.
maybe her scent
in the brief moment she passes
by him and he does not see.

So it was like this:
She didn't see it and he passed!
