Polly was nervous and barking when the roofers came to replace our roof yesterday. I carried her around a bit to distract her then I needed to set her down and get some work done. I pulled out the dining room chair and set her there since she is never allowed to sit there. She sat quietly and contently while I worked. To my surprise, she was still there when my work was done. Today the roofers finished and she is back to being calm.
