Oxymoron

Goodbye is the ultimate oxymoron.  Think about it for a minute.  What exactly is good about expressing farewell to someone you obviously feel strongly about and sufficient kinship to that you wish to be present when that person takes leave of the situation they currently find themself in, all too often against their will and better judgment?  Nothing.  There is nothing—Zero!—good about emotional departures such as those, hence there is no valid reason to characterize the words spoken at a time such as that as anything other than sad, bad, mad, or saturnine.  Settle for the “bye” part and cast aside the inappropriate and dumbly used “good”.
