We used to have a cat who hid all night in the bedroom when company was over, which she didn't like at all. Around 11 PM, she'd come out and sit opposite the guests and just glare at them. The first time it happened, a good friend looked at her and said "Oh, look! She came out! Oh...and she's definitely telling us to get the fuck out!"

I was convinced that she believed she was communicating telepathically, just because we could read her expressions and know what she wanted. As far as she was concerned, she was controlling us with her superior advanced brain.

And I guess she was.
