Unexpected Turbulence

     You've almost reached your cruising altitude and the captain has turned off the seatbelt sign.
    But you've flown enough to know it's best to leave your seatbelt fastened.
    In case of turbulence.
    Or whatever.
    And then the guy next to you asks a question.
    "What," he says, "is the meaning and purpose of your life?"
     Startled, you turn to look at him more carefully.
     "I'm serious," he says. "Why were you born?"
     Well? 
      "It's a fair question," he continues.
      "After all there are people these days who find a meaning and purpose by  killing themselves just so they can kill a few others."
       And then, with a strange grin, he reaches under his seat and pulls out a package.
       "What'd you think I've got here?" he chuckles.
