One Shove

One massive push and we will shove the cart
Over the cliff, into the ocean. Why
It seems so heavy that we have to try
As hard as this, we reckoned from the start:
Inside it is your overgrown, dead heart,
The one you wasted. Watch it almost fly,
Regard it soberly, and shout good-bye.
Those rocks will break the residue apart.

You should have also used the left-hand glove
To keep from getting slivers in your hand
And scratching up your golden wedding band,
But you keep waving at your feckless love.
Just give the thing one last, decisive shove,
And move on. Push! What don't you understand?
