@dgar You get that from pilots too. As part of the passenger briefing when taking some mates for a ride in a light aircraft:
"Don't worry if I start talking to myself. This is perfectly normal, and is a habit developed during training when you give a running commentary to the instructor.
"Also you *probably* don't need to worry if I swear at myself. It *usually* only means that I've done something slightly less neatly than I would have liked."
The bit you try very hard not to say out loud when you have passengers is, as the wheels leave the ground:
"Hey, the only way we're going to be alive in an hour's time is if I don't fuck up."
