Hello friend @wiseagent, you are right sometimes you should keep silent, especially when we are in front of people with bad intentions, because they transgress the information, but I think we should know how to say things, because there are people who consider themselves sincere but are cruel with their words

If we have tact when saying things I think that will allow a fluid communication, as they say there talking people understand each other and clear accounts keep friendships.

See you later dear friend, good job !
