Always walking by the river, how can you not wet your shoes: describe that you always do something and you will miss it sooner or later. A straight body is not afraid of a curved shadow: no matter how straight a person stands, the shadow is still curved. But no one will say that you are not standing straight just because your shadow is crooked. Integrity means that if you are honest, even if many people speak ill of you, you don't have to be afraid, because you are honest.
