what was once one, was only once
what is to be, might be
what is now, will be the past

what was once whole. is now only part
what was once there, may be gone
what was once past, will never be

what was once a part, is now gone
what is now gone, is only  a memory
what will never be, is now forgotten

now it is gone
once a memory
is now forgotten

and no longer
in the past
