Its about people who leave other people behind basically. Like for example people who are there for you and then they leave you. Its very metaphorically written The River is suppose to be about heaven like a vale and the boy I'm talking about cannot see the help but it's there.
Also its about my ex in a way. How I let her down, part of my past now. And also that her ex boyfriends beat her badly. And yeah.....
Its a hopeful song.
