Things that get lost

Wait a moment,
don't walk so fast
I think I knew you
once upon a time
but I didn't see you up close
and so I can't be sure
that you were the person I once knew
your hair is different
your clothes too-
but then again, that's not too hard to change
you weren't smiling-
but then again, you weren't one for smiles
and happy things
was it you,
I wish I could call out your name
but I can't-
it got lost somewhere near the top of my throat
and worked it's way back down-
some things should be left
as they are-
so you keep walking
and I'll stay wondering-
some things you don't need to know
I suppose...
