Sometimes we see pictures of movie stars or models who have a little black dot on their face and we call that dot a beauty mark. Sometimes, when we see a dot on someone else's face, we call it a mole. At what point does a mole become a beauty mark and at what point do we classify a beauty mark as a mole? Is it the location of the dot? Is it the size of the dot? Or, for instance, is it always classified as a beauty mark if it is on a beauty star?
