Did you know your brain hemispheres are actually two separate entities? The left controls language, and the right side of your body. The right is silent, it has no language with which to speak, so your whole life you're thinking you're this one entity, when in reality you have a silent partner tagging along taking orders because...what the hell else is it going to do? Rebel and cause the whole system to crash? No, it wants to live, so it silently helps and rolls its eyes every time you think you're alone in there.
