Every time I fly I am reminded of my favorite Seinfeld quote:
Elaine: I hate people!
Jerry: They’re the worst.
Hour four is usually my witching hour on a flight. That’s when I morph, Incredible Hulk-like, from a fairly patient being who has been known to go out of her way to hold the door open for others, into a real live George Costanza, ready to snap at annoying strangers.
