Often one is right and the other is wrong but still one has to keep mum and not be straightforward so as to maintain a level of diplomacy and get carried of in arguments and grudges.
Often there are people with money power and some authority passing wrong judgments and one has to keep mum , so as to avoid their ego-centric lower level getting back to you for your outspokenness attitude but WHY SHOULD THIS BE ?
JUST BECAUSE THEY have everything except a sound judgement or reasoning and one has to keep mum so as to avoid their being grudge-full against you as you never want to face their wrath and still have them as your patrons ?!
if only things were simpler …
