Former students from a technical university in Brno have maintained a unique friendship for over fifty years. The tradition began during a student trip to Pustevny and survived wars, regime changes, and a pandemic. The group established their own set of rules, including fines for forgetting an index or missing a meeting without an excuse. They also created a chronicle and their own anthem. This long-term bond grew organically over the decades. It remains a lasting connection among former classmates.
