The Letter

I don't know, I kind of feel like it's one of those situations where someone he used to have feelings for comes back into his life and she wants to be in a relationship with him again, but he knows that they're not right for each other, so it makes finding love harder with her around. The part where he says "I know, I know, I know" kind of makes me think that he's tired of hearing her excuses, which she may have written down in a letter. The part where he's talking about all that he's lost, he might mean that he is not going to be in a relationship with this girl again and watch her leave, but he's curious to know anyway. And when he talks about her walking blind in "here", it could possibly mean that he thinks that they're blinded by love. Then the part where he talks about washing her heart in the river, he might mean that he wants her to forget about whatever feelings they used to have for each other so that they can start anew. At the end of the song, he's just saying that he needs to say goodbye to her, but he wants to say it right.

Well, I'm not sure if any of that is right, obviously, but that's just what I think.
