Yes, perhaps I should be paying more attention, whenever flying, to that steward or stewardess who is explaining to me the function of the life preserver stored under my seat and what to do in case of a plane crash. Good point. Point taken. Beyond that, given an otherwise uneventful flight, these people are not necessarily my friends. I do not know who they are and what they are scheming and plotting my back and I do not necessarily trust them to have my best interests in mind.
