Our dear dog Copernicus did something ingenious yesterday. While Tim Miller Construction was here installing a storm door in front of the kitchen door, Copernicus and Alice were secured in the master bedroom. I closed the sliding door connecting the master bedroom to the living room. I thought that all was well. Someway, some how, Copernicus opened the door. He and Alice came into the living room. I had to secure them while Tim and his son finished their work.
