Softness overcomes all the hardness in the world, whatever in psychology or in physics, it's no lie.
Soft guy makes tough guy become soft, may it be visible or not, inside of him becomes soft, it's just metter of time. Same with rock, water makes the rock dull. Water is adaptable and without shape, if you put it in tea cup it'll become a tea cup, if you put it in can it'll become can.
