A short while before departure time an older lady asked one of the Flight Attendants to check on her husband. The Flight Attendant asked where he was and received a questioning look from the lady. Not understanding, the Flight Attendant asked if she knew his seat assignment. Now the lady got a pained look on her face and was about to break down in tears. The lady finally explained that her husband had just died and she was taking him home. He was in the cargo bin. Needless to say, the Flight Attendant just about died of embarrassment.
