Misty knows when it’s Thursday at 4:45. It’s time for her human’s piano lesson. As the piano begins to echo throughout the house, she comes trotting into the living room to find my lap. If my student or I leave our seats, she immediately replaces us. Sometimes Misty will even interrupt a lesson by getting in the way of my student’s hands while he plays. “She only does this when you’re here,” I’m told.
