I remember my first day on line, looking out the side window....thinking.."I shouldn't even be here", so I said to my Captain 'shall I start my briefing now?', no he said, just start the engines.
Same guy later on said, 'do you want the full brief or the standard one?'
Standard will be ok, said I.
OK he said,"Standard".
Roger, just out of interest, what was the full brief going to be, I asked?
"Standard for 23".
To this day I cannot be bothered with long briefs. Listening to them is more of a challenge than giving them.
