something you don't expect
dear diaz:
if you are sitting in your home and a meteor hits it, that is something you might not expect.
If Raquel Welch showed up at your front door, that is something you might not expect.
BUT FOR A PILOT in a storm condition that was making headlines all across europe TO NOT BE READY FOR A WIND CHANGE is NUTS.
YOU EXPECT the worst until you have parked the plane and someone else has the watch. IF NOT, YOU ARE NOT DOING YOUR JOB AS A PILOT.
