The Dark Side of the Moon(Temna stran lune)

Žan is in the seventh grade and an excellent student. He is dedicated to astronomy most of his time and is much better than his coevals so in the school club he is the one selected to participate in the republic competition. A year ago, Igor, a nine grader was as well at the competition. Although he was successful, the second place he won was not good enough for him, so he gave astronomy up. Now, however, he is witnessing Žan's success and becomes very envious.
