It's never easy to say goodbye To the faces So rarely do we see another one So close and so long

I like to think that this verse reads "It's never easy to say goodbye to the faces. So rarely do we see another one so close; and "so long"' As if he is saying that so rarely do we see another person so close (so intimately) before one has to leave again. At which point one must again say goodbye, or as my grandfather would have said "So long" hence the "...and so long" (ending the interaction with a goodbye, starting the whole cycle over again).

Highly doubtful that this is how it was intended to be read, but I so rarely hear anyone say "so long" anymore and I find the possibility of it being used in this song so very familiar and touching.
