I suited up early this morning, intending to be out the door well before 7.  I know that my daytime minutes start at seven a.m., and that any call that starts prior to 7:00 gets entirely counted under night and weekend minutes.  
Jody lives in Atlanta, and works the overnight shift.  I don't call him as often as I should, but the timing of our lives means that he is finishing up his day as I am readying to start mine.  I take a perverse delight in making sure my calls to him start just a couple of minutes before 7, with earpiece tucked securely in my left ear as I drive.
