The alarm sounds at 0500. You roll over to shake your Sailor or Marine awake, only to find it's your 4-year-old snuggled up on the other side of the bed. Suddenly it all comes back to you. You remember standing at the pier, flight line, airport, driveway (pick one), and saying goodbye with your heart in your throat. All you want to do is cover up your head and sleep until your spouse returns, but the beeping of the alarm reminds you that your family and job still need attention, and life won't give you the luxury of a six-month nap. So you get up, and you go on.
