Right up front I tell students I get pretty intensive in the cockpit

don't go overboard with any profanity (depending on who you talk to)
but the intensity doesn't ease up.

I believe the scientific method says you should have tried instructing
without the profanity and see if it made any difference in your success
rate and student's perception.
