Reminder
Mumford & Sons Lyrics

The opening lyrics of "Don't let me darken your door, it's not what I came here for" suggest that the singer is aware of their own negative tendencies and doesn't want to bring any kind of trouble or burden to the person they're speaking to. They seem resigned to the idea that they might not be good for the other person, and acknowledges that they don't know if they're doing anything wrong or not. This implies that there might be a fear of damaging or losing the relationship, which sets the tone for the rest of the song.

The chorus "Constant reminder of where I can find her, a light that might give up the way, is all that I'm asking for. Without her I'm lost. Oh my love don't fade away" conveys a sense of longing and desperation. It's as if the singer is lost without this person, and that they're always searching for some kind of light or guidance that will lead them closer to her. The line "without her I'm lost" is particularly poignant because it suggests that the singer might have nothing else to hold on to, which adds to the vulnerability and fragility of the relationship.

The verse "So watch the world tear us apart. A stoic mind and a bleeding heart. You never see my bleeding heart. And your lights always shining on. And I've been travelling oh so long. I've been travelling oh so long" portrays a sense of inevitability, as if the singer is resigned to the idea that the world might tear them apart. However, there's a sense of strength in the face of this, with the idea of a "stoic mind" that's able to withstand the pain of the "bleeding heart." This could be interpreted as a kind of defiance in the face of difficulty, which is further emphasized by the continuing journey ("I've been travelling oh so long")
