I called out his name and he looked at me. "Can you go to the end of the hallway and pick up Bimbim?" I told him. He looks at me then he looked at the fire exit. So I answered him " No, I think Bimbim is at the end of the hallway - I can't really see her because she's black but just go get her." Once again he looks at the fire exit, so I told him "Just go to the other side and get her". So he starts walking in his slow lazy manner. When he gets to the middle of the hallway he starts meowing, I told him " I didn't tell you to call her, I told you to go pick her up." He continues meowing and lo and behold - Bimbim comes out of the fire exit. Shamefully I had to apologize to Sumo for doubting him and scolding him. Nice to know that he knows where Bimbim is even if I don't.
