Developing Give&Take analysis

It was little difficult for our students to analyze Give&Take relations in Moomin story, because they were troubled with finding what a character could took at the end of the story. They thought too difficult to find it. They tended to think abstractly. But I would like them to think more easily and find concrete things. It is equal to a difference of a character's conditions between the start and the end that what the character can take. For example, in "Moominsummer madness", a park keeper could emit light from his whole body, because he was surrounded by many Hattyfatteners who take a charge. So they could take a body which emit light. It is easy to find it. Rather, it is more difficult and important to think its meaning, that is, what is it a metaphor of? Let's think about the previous example. What does a body which emit light mean? At the beginning of this story, the park keeper had robbed freedom from the others by setting up many billboards of forbidding. In other words, he could shine by robbing lights from others. So he could shine by himself when he interacted with moomins. In this way, I would like to develop this method from the viewpoint of changes of a character's situation.
