A tradition becomes fragile when understanding is replaced entirely by obedience.

A practice survives on the reasons handed down with it. Where only the rule is passed along, the next generation inherits an instruction with nothing behind it, and instructions without reasons are brittle: they cannot adapt, cannot answer a question, and break the moment somebody asks why. Obedience keeps the form going for one more round. Understanding is what lets it last.

If you keep a tradition, make sure somebody knows the story behind it and tell that story out loud occasionally. Welcome the question rather than treating it as a challenge. A custom that can explain itself can also survive being changed a little.
