What is the meaning of no rule is so general that there isn't an exception?

The phrase "no rule is so general that there isn't an exception" suggests that while rules and guidelines may apply broadly, there are often specific cases or circumstances that deviate from these norms.

This concept underscores the importance of flexibility and critical thinking when applying rules in real-life scenariOS. Ultimately, it serves as a reminder that exceptions are a natural part of any system.
