gotta set the scene a little,
I'm a student skydiver and us students are known for being extremely nervous on the flight up to jump run, our brains are racked with getting all of the procedures right.
going up for the 2nd jump of the day with a load of students, just after takeoff, the jumpmaster asks, "what's your altimeter say?" as we're all looking down at our altimeters, "nothing! altimeters don't talk!"
