I don't really know Aiden very well and only know like two of their songs, so I don't really know their style or what they really sing about or if they're talking metaphorically or anything so don't get pissed if I say something that isn't right.
Anyways, I think it's about having a friend who died by committing suicide. I don't know. Don't blame me if I'm wrong, since I typically am wrong.
