On a separate, but related topic, stupidity like mediocrity is relative. Relative to your relatives, mine, or other people’s but, if you prefer to appear more subtle and empathetic, relative to the subject at hand (and/or the intelligence (or not) of the deliverer). In the unforgettable words of Forrest Gump ‘Stupid is as stupid does.’
