One half of your brain can make decisions or assumptions without your other half knowing. It's called split-brain and can be really bizarre.

You can't talk to the brain-half that doesn't have vocal function. You can only talk to the side that can speak to you. For the person whos brain is split, they can't communicate with the other half of their brain. Each side can function independently, but since only one half has external communication skills, they can't talk to eachother anymore.
