Constant Companion

With a shadow of doubt the past casts its silhouette
Its outline stays sharp despite the sun being set
At times its elongated form extends straight out ahead
Or sometimes following behind as if being lead
But whichever way you do look it sticks to you tight
And it doesn’t need darkness and it doesn’t need light
It only needs memories (and you’re in all mine)
Yet even in the shade there’s a little bit of shine
So I’m trying hard to believe that a light will always shimmer
Even if a shadow of doubt will be created by its glimmer
