This person lets out a whimper at every bump and creek. God forbid the flight hits turbulence - they will be saying hail marys before the captain turns the seat-belt sign on. And don't waste your breath trying to calm them down. If they'rein that type of state, nothing you're going to say is going to help. Maybe slip a sleeping pill into their club soda and knock 'em out. Just kidding. Don't ever put pill into anybody's drinks without them knowing.
