Some cracks become dangerous because cosmetics arrived before investigation.

A crack painted over does not stop moving. It carries on doing whatever it was doing, only now nobody can see it and everyone assumes it was handled. That is how a manageable structural issue becomes a serious one, and the same pattern applies to problems in teams, families, and bodies.

Before covering anything up, find out why it appeared. Investigation first, appearance second. Reversing that order is how small faults become dangerous ones.
