Cover art for Flake lyrics by Jack Johnson

I think this song is about trying to get back together or forgiving someone in a relationship. It seems that he made a mistake in the relationship, which she says is fine

"I know she said it's alright But you can make it up next time".

But in reality, when he talks to her about getting back together or forgiving him she always tells him maybe, and he is realizing that she simply can't let go of whatever he did and he's getting tired of it:

"It seems to me that maybe It pretty much always means no So don't tell me you might just let it go"
