For they may reverberate as they travel further and further from the point of origin, and grow fainter with each repetition...
But those that listen and remember can sometimes still hear them.
It goes without saying that by the time an echo is picked up, much has changed at the source. For instance, this hobbit lass found her journey from the Shire side-tracked. Three years later, she has rediscovered her old journal, complete with water-stains and ink-smears.
And she treasures it, all the same. But she also has a new journal, and a new outlook on life--the result of a road traveled and others untraveled.
But there will be time to discuss that later. For now, know that echoes are still heard.
