No One Can Know

Shay and Andy are like twins, they know everything about each other, they are always together, they finish each others sentences, and know what the other is thinking.
They also happen to be polar opposites, while Shay is loud, preppy-ish, girly, cheerleader, Andy is a more quiet, closed off, tom boy-ish, artist, they don't have any problem getting along. Andy goes to Shay's cheerleading practice and Shay tags along when Andy goes to art classes.

They don't do everything together but they are seen together more often then apart. They are parners in crime and sisters at heart :)
