That is fantastic! I had a box turtle once who would bang on the glass door to come inside. His name was the Saint because I rescued him from falling off the sidewalk into the street in front of a church in Athens, Greece. I was hoping my fish, named Yoshimi (from the popular song), would come over and ‘talk’ to me every day. I wait for her to come over and then I feed her. But I expected that it was more of a learned response of coming over to get food. But then she did it more often, even when she wasn’t hungry, so the questions started to come and I googled it and here I am!
