What a great story! I had a cat once who, every time I was upset, would start spinning so fast that all you could see was a whirling circle of white. Then she would stop and fall over in her dizziness, her eyes looking disoriented and her head moving from side to side. It was absolutely hilarious and worked every time to turn my sadness into roaring laughter, at which she would look mortally offended and stomp off. I am damn sure that she did this because she wanted to make me laugh to cheer me up, but whether the offended storming off was part of her act or not, I could never work out!
