Might I suggest a new briefing from the captain:

"Welcome aboard. Since I'll be pilot flying and he'll be pilot monitoring, consider yourself pilot monitoring the pilot monitoring. Because we're working 14 hour days and 7 legs per day, we're going to make a mistake at some point. Perhaps you just might be the person that traps that error and averts the NTSB from having to write those long tedious reports. And of course the local morgue here (insert outstation) is probably over worked and under-staffed as well, so they really don't want to come out and piece body parts together.

I know you really don't know our SOPs but you're obviously a pilot so if you see something wacky, ask. Since I have sleep apnea, am 40 pounds over weight, and my hearing is shot from flying Convairs for years, I am likely not on my A game. Also, because this person next to me is 30 years my junior, he will be unwilling to question me for any reason or speak up if we are going to fly into a mountain. So do it instead. Besides, he slept in the crew lounge last night since 22K a year can't get you living quarters in (insert airline hub here). So the level of alertness in this cockpit is really crummy. Better yet, even if I don't talk to you or even flat out ignore you - I have irritable bowel syndrome from those years of airport food - just consider yourself part of the team, take the I-pod out of your ears to maintain SA, and help keep us alive and out of trouble.
