The mark of the prince, in palmistry, signifies a personality which (when presented with a person of much lower behavior) is willing to take on much lower behavior themselves when dealing with that person
But this mark, which once described me, is based on a false understanding: that the other person is operating with low behavior. They're not. They (as everyone) are always operating at their best. A person appearing to the prince as showing lower behavior, appears to the king as a person showing their best, most highest, behavior. The king also knows that the only thing to do when someone else is doing their best, is to do my best as well
