I get the impression that it is about a person trying to remain "invisible" in life, and simply get through their life without impacting on anyone or anything. That is they spend their life just waiting for the end.
The other side of the coin could be that it is about ignoring others (or social issues) that don't directly affect you. If it doesn't affect you don't care ... ignorance is bliss (some might say)!
