I don't know if you have noticed this, but it is quite possible for two human beings to have a conversation in which one or both parties involved has absolutely no idea what they're talking about.
This world is not my home, I'm just a passing thro', My treasures are laid up somewhere beyond the blue; the angels beckon me from heaven's open door, and I can't feel at home in this world any more. 0 Lord, you know, I have no friend like you, if heaven's not my home then Lord what will I do; the angels beckon me from heaven's open door, and I can't feel at home in this world anymore.
