The relatively common phrase, "Those that live in glass houses should not throw stones". If you live in a glass castle, is it wise to point out the weaknesses of another king/queen who live have their own problems and weaknesses? The simple answer is no, if you start insulting, judging, or "throwing stones" at others, your glass castle will likely be broken or shattered by someone (throwing stones) pointing out your weaknesses, faults, mistakes when judging you
