In the moment of danger, people drop their masks and become themselves, and their true faces are sometimes not good.
Not everyone wear masks. Some people are showing their true face in their pure honesty. But only a few. Or at least nowadays I know only a few. They are always straigth and honest, and they always tell you the truth. They are always honest.
As I see it, nowadays this is a real rarity. These personality traits and behaviors are very valuable. Especially if it is true to someone amongst your family and/or amongst your friends. They are reliable, and you can always expect the best from them. They are the best friends.
