To further expound upon this, unlike a die, a human potentially has more faces than can be seen. To wit, the better you know someone more apparent their other faces become. Furthermore, the more faces a person perceives of another person, the more they can still see those other faces? When looking at the face of a four sided die, one face is clearly visible, but on the other hand, you can see more than just one face at a time, even though one is in focus.
