Typically "Hi Petey!"s are reserved for the Boy. When he's not there and Petey's figured it out, he stops until he comes back.
Well tonight...it was a different story.
I was out with coworkers for a large portion of the evening and the Boy was home with the birds. When I came back home, they were still out of their cages. Petey flew to an atom the moment I came in and started saying "Hi Petey" and repeated this a few times. Since the Boy had been there all this time, they did seem directed at me.
It made my day!
