Seppi is almost 14 years old and is going through all the problems that come with being 14. A mother who knows better than everyone else. A father who has no clue about soccer. A grandmother who would love to fatten him up. A classmate who is incredibly annoying. A best friend who has been acting strangely lately. One thing is certain: FC Bayern is the best club in the world. And Seppi has to participate in the Christmas play directed by the feared principal. In his diary, Seppi reflects on these thoughts. A delight for all students and anyone who enjoys reminiscing about their school days.
