Why they are a killer....
  1. The interrupted sleep
    You know you have to get up at 2:30am and wake up every hour to make sure you don't sleep through the alarm
  2. The alarm!!!
    How come every time it goes off especially at 2am you have just drifted off into deep REM
  3. Nothing's open!!
    Everything's shut at the airport until at least 4:30 so you have to hang around like a loser.
  4. This includes Customs
    Have a funny feeling they open at 4:30. So here I am avoiding the line
  5. I know the above is trivial
    But the fact that you are about to jump on a plane to go somewhere exciting makes up all of the above!!!
