"Shame" by The Avett Brothers

The subject of the Avett Brothers' "Shame" is shame, and the tone of the piece is regretful. The phrase "I'd like to see these [untender and untrue] thing undo" illustrates how the speaker is regretful about his past actions. He clearly regrets what he's done when he says "boatloads of shame" because the connotation shows he recognizes what he's done is wrong and feels bad about it. "I've had time to look around and think and sink into another world that's filled with guilt and overwhelming;" this line states outright that the speaker has thought about his action and regrets them now.
