I'm impressed that you are able to discern the full range of my notions about public vs. private behavior from an inconsequential post on an inconsequential thread.

Of course, as others have pointed out, this was obviously something either approved by or concocted by handlers, and they're the real pros, so don't get shook up by what a country boy like me thinks...
