the law of similarity

the law of similarity in sympathetic magic implies that a fundamental and real connection exists between similar objects and this can be used in magic. This is interesting, because in a movie about kids, the story about Cheese is interesting. It portrayed that there is a piece once laying on the playground of an elementry school, people were grosed by it, and they think that piece of cheese is grose and disguisting. no one want to have anything to do with it. then a girl came, says: on tom touched the cheese! then every children isolated tom, don't want to play with tom, don't want to touch tom, have nothing to do with tom. then, tom feel bad about his isolation adn everything, so at lunch table, he secretly touched Luch, spreading the germs to lucy. now everyone hates Lucy: Lucy touched the piece of cheese! then it spread around and around and around until somebody touched the german exchange student, he does not know what's going on, and finally brougt the law of contagion to Germany. Interesting!
