Sometimes you can't come home

Not a concept I've ever embraced, but listening to "The Jefferson Hour" this week, Clyde Jenkins was discussing Merriweather Lewis' failure to adjust after the long trek through the Louisiana Territory and said (paraphrasing someone else I failed to note): "How far can you go out before you can't come back?" I think about Terre that way, that he just got lost and couldn't get back. Or became someone else, really.
