The parents are often to blame (Porphyrios of Kavsokalyvia)

Very often it’s the parents, particularly the mother, who reprimand children for misbehavior and shout at them quite unfairly. Then they’re wounded. Even if you don’t chastise them visibly but you feel it inside yourself, and you’re frustrated or look at them angrily, they’ll realize. Then they won’t accept affection, because it’ll seem hypocritical, because they’ve been hurt.
