Filling Trenches

you rest easy, while i try to fill the trench you dug. heavy shovels full, one upon another, i try to lug. the hole never seems to fill. trying seems in vain, as the old tune plays in the background, singing of those times before. oh, it seems so much harder while the sun shines so long and hard on my back. should i simply leap into the hole? perhaps then, you could take over filling the hole. with me inside.
