A correction that stings can arrive as friendly information or as a sentence passed on the whole of a person, and everything turns on which the mind hears. When feedback reaches someone who has forgotten its purpose, they either wave it off as an insult or crumble under it as proof they are worthless. Both readings miss what it carries.
The mechanism inside us steers toward a goal the way a guided missile does, reading each miss and correcting. A rebuke is that same signal, sent by a source that wants a person to arrive. The father's hand is not against the one it shapes. Taken as steadying rather than as a verdict, the sting becomes a direction, and a person stops mistaking guidance for condemnation.
