Ghosts under Lamp Posts

Do lamp posts
Show, by their fitful glow
The ghosts
Of sinners long ago?
And, on seeing that fitful glow
Do dying men go
Back, down that dark track
And perceive
Ghosts under lamp posts.
And, if so
Do they grieve
For the money spent
On cheap scent
Long ago?
Perhaps it is so,
But That, I can not know.
