People mean what they say? Oh that would be nice, Seedy. I have
   to disagree. I _wish_ people were that straightforward but I
   think duplicity is quite everyday and common. Just look at the
   popularity of sarcasm. As my nephew puts it, "saying the
   opposite of what you really mean". Some people wear it as a
   badge of honor that they have this capability. That's not saying
   what you mean or meaning what you say - and sarcasm is about as
   basic as it comes. Some people get even more twisted in what
   they are saying vs what they're 'really saying'. Implications,
   inferences, suspicions... unfortunately words and sentences and
   logic alone are not always enough to discern intention.
