Life is hard
     
        [XEROX PARC] This phrase has two possible interpretations: (1)
        "While your suggestion may have some merit, I will behave as
        though I hadn't heard it."  (2) "While your suggestion has
        obvious merit, equally obvious circumstances prevent it from
        being seriously considered."  The charm of the phrase lies
        precisely in this subtle but important ambiguity.
