Every tale is not to be believed. Everyone is more or less master of his own fate. Evil companions bring more hurt than profit. Evil tendencies are shown in early life. Evil wishes, like chickens, come home to roost.
Example is more powerful than precept.
Fair weather friends are not worth much. False confidence often leads into danger. Fine feathers don't make fine birds. Happy is the man who learns from the misfortunes of others. Harm hatch, harm catch.
