I has a trick. A Jedi Mind Trick.
I learned a long time ago that my Nonna thinks it's the cutest damn thing when I talk to her. She says things like "Gooood Giiirrll" and "Well bless your heart" and then I get cookie treats. I usually begin the process the moment I walk in the door. I used to just talk and roo, and rurble, but I've learned that if I just cut to the chase and bark my asses off I'm rewarded right away. As soon as I hear the magic word I feel very accomplished, and I accept my reward proudly.
