HAVE A GREAT DAY! HAVE AN INERESTING DAY!

Everyone in the monotonic society and culture around the US resort to the  commanding phrase: HAVE A GREAT DAY!  And, I ask many of these spewer forths of such froth, 'WHY SHOULD I? Why can't I have a bad day!  And, who are you to give me a good or a bad day, if I don't want one?                                                                                                                                                                  However, I suggest that we now bless others with this mantrum: HAVE AN INTERESTING DAY!
