Good point.

What do you do if it's a late show trip flying into midnight and your fellow crewmember had to get up early? He/she had wake up and watch the the kids all day while the spouse was at work because they "chose" to move to base and away from friends/family that may be able to help out.

Wait, rich airline pilots (especially FO's) can afford day care all time and/or a nanny, never mind.

Isn't playing devil's advocate fun game?
