Just whos folly is it anyway?

It is arrogance to attribute our own folly to others. To say that “we all do  . . [this bad or stupid thing or that]” or “if we are honest with ourselves we all do/think  . . [this bad or stupid thing or that]” . Like, "we all eat too much fat" It might make us feel better, or at least smugger and wiser, but the truth is that not everybody shares our weaknesses - but it is more humble to understand some people have overcome things that we have not.
