From my home office window, I saw the USPS mail truck drive by.  A few minutes later the doorbell rang.  I ran down the stairs and opened the front door to find no one there and no packages on the porch and no mail on the javelina snout.  Huh, I wondered and literally scratched my bald head.  Mom was sitting calmly at the kitchen table.  “Mom, I heard the doorbell ring, but nobody’s there.”  She allowed a sheepish grin and told me it was she that had rung the bell.  At my quizzical look, she confided that the doorbell is a kind of intercom message from her to help Dad get up and get moving into the day.
