Echoes

Ghostly echoes, heard, return,
As shadows of themselves,
Bouncing off the hollow walls,
As if canyon deep,
Returning half of what they were,
When first, they were expelled,
Just like a whisper in the night,
Originally yelled,
And soon they fade,
Into thin air,
Like frosty winter breath,
As if they died,
Before their birth,
So short they live till death,
And so the echo's lonely friend,
Again gives out a yell,
As if he's talking to himself,
As far as I can tell.
