My watch alarm went off today at 11:45 and I felt lost.  I had reset the alarm so I could sound the squall drill at the Klondike but for the last three years my watch has gone off at 7:25 PM and 7:30 PM.  I can’t remember why I set them in the first place but they’ve been part of my circadian rhythms and a stuttering double  beep mean “night”.  Five minutes later, I’d receive another set of beeps to remind me of “night”.  Now, I’m completely thrown off.  I’m like an owl stunned by a lighthouse.  I need to reset my watch before the beeping becomes a Pavlovian response for lunch.
