The Avet Brothers sing about losing someone that they love and use a weary tone to show their struggle. This weary tone shows that the author believes that a broken heart can lead to a  large, weary souls. One phrase that demonstrates this theme is when the singer sais 'boatloads of shame" the boat symbolizes the emmensity of the same that he is feeling. The author also shows that resenting something can make one weary. He does this by using the word "blame" a lot to show that he is resenting something that he did and it is making him weary. Finally, the author said "let it(heart) fall" this shows that the heart heavy with blame can be resentful, theirfore falling.
