Definitely PunK! I think it's more like thinking out loud for me. Except when I talk to my cats, which I do quite a bit. I actually have one that 'talks' back. When I talk to her she always responds with a meow after every sentence! I suppose she thinks I understand her LOL! It is really funny! I think it's normal but when other people hear her talking back to me they think it is hysterical!
