Common sense is not so common. It’s a misnomer. On a Friday/ Saturday night when there is intense emotion, boredom, alcohol, illegal substances etc, then there appears to be a lack of common sense. Common sense should be called wisdom and wisdom is usually gained through trial and error or when you make the right judgement when weighing a variety of factors in an ordeal e.g. an example of wisdom would be neither being brutally honest (Honesty virtue) or being completely dishonest (Dishonesty vice). I think that is what’s “common”.
