This song is defenatly going back and fourth between a man and a woman. The woman is feeling lost without the one she loves, but she doesn't know that the one she loves still remembers her and cares about her. Before he left, he used to make the world better for her, and their little talks are what she remembers about him and how he used to make her feel whole. In reality, the man does care about her and wants to comfort her as much as he can.
