Right Thing
     
        That which is *compellingly* the correct or appropriate thing
        to use, do, say, etc.  Always capitalised, always emphasised
        in speech as though capitalised.  Use of this term often
        implies that in fact reasonable people may disagree.  "What's
        the Right Thing for {Lisp} to do when it sees "(mod a 0)"?
        Should it return "a", or give a divide-by-0 error?"
     
        Opposite: {Wrong Thing}.
