Acquaintances

I've been seeing old faces
in people I never knew existed.
I get the urge to call out to them,
but by the time I get the chance to,
I realize they're not really there.
I've been seeing old faces
of people who didn't mean much to me.
I'd see them occasionally in the hallways
of years past,
but never got to know them.
I've been seeing old faces
of a time that would be jealous
of the place I've created for myself today.
What is it with nostalgia
and creating physical personifications
of memories that seem meaningless?
