Our local post office had a beautiful Norfolk pine in its lobby.  For a long time (several years) it was a flourishing tree. It must have liked the the light it was getting in that spot.  Then it started losing branches and started dying.  There seemed nothing our postmaster could do about it.  Once a branch becomes brittle and breaks off it is too late.  Some of the branches were still healthy.  Finally it died.  I had the image in my head how healthy it once (???).  I felt so bad when she took it out of there.  She suspects it got over watered.  It was so beautiful once.  And now its dead.  I just felt bad for it.
