Standing at the corner of Yesterday and Tomorrow

Standing at the corner of yesterday and tomorrow…

Standing at the corner of yesterday and tomorrow
and the light is changing from reflective yellow to go;
decide, you must.
See the image upon the storefront glass,
your shadow from within, pointing towards the west?
Do you see it there? Will you listen?
Do you even recognize the whispers from within?
To remain is not an option, for time carries on,
but will you choose to step in to the future or to live in the past,
when standing at the corner of yesterday and tomorrow?
