The message
from John Cartmell contains these words:

*In this context human behaviour excludes written or oral communication.

I take back some of my 'ignorance' comments. You are starting to think. Yes
written and oral communications are part of behaviour.

I have had my say and this is starting to go round in circles so I think
we should bring the discussion to a close while we are at least being
almost polite to each other.
