Since I retired, and except for mornings when I have an early appointment, I have rarely used my alarm clock. Instead, one of our Scottish Terriers, Tillie, provides me with a wakeup bark. Usually, between 6:30 and 7:00 AM, she’ll let me know it’s time to get up. She’ll also get more insistent if I ignore her, or if she feels that I am taking too long. Then she’ll whimper in a classic appeal to emotion. Then it’s time for our morning walk and breakfast.
