“More Muttering from the Rabbits” is a celebration of life, as was its predecessor, “Silence of the Bunnies.” The difference is that “Silence of the Bunnies” represents my reaction to being told that I had Parkinson’s, and “More Muttering from the Rabbits” represents the twenty-three years I have lived since. In both cases, I try to appoach the facts as I found them with grace and humor.
