The best was after a trip or three and the old timers (including Masters and CE) got to talking and telling you the mistakes they made in much less forgiving times. You quickly realize no one was born on the throne they seemingly occupy when you’re new.
Also, an officer once told me that if the old timers bust your balls and give you a hard time about things you did, they actually give a shit. If they wanted you gone they’d just allow you to keep working on your own noose.
