Part of the Brain

I have a theory. People who are extra-creative have a part of their brain missing--the comon sense part. Could it be the brain matter responsible for creativity, pushes the part in charge of relationships and good sense out the left ear or squeezes it over in a corner under the earlobe, making it unresponsive to ordinary people situations. Take a second and think about it. Who do you know who is talented in public areas but sucks in private? Me, I know lots. Maybe one in the mirror.
