That moment when you are disappointed at your parents for still showing signs of emotional immaturity, most noticeably:

Denial of the reality: Even if the evidence is against them they will refuse to discuss (mostly because they feel they always must be right) - increased probability while angered

Projection: Attributing one’s own unacknowledged unacceptable/unwanted thoughts and emotions to another; includes severe prejudice, severe jealousy, hypervigilance to external danger, and “injustice collecting”. i.e blaming another for self failure, harshly criticizing other people while not realizing they think the same way as him, keeping all the wrongdoings someone did to him, maybe even using them in an argument, even years after.
 

Displacement: the mind redirects effects from an object felt to be dangerous or unacceptable to an object felt to be safe or acceptable. i.e screaming at you out of nowhere - increased probability if they are stressed/had a bad day.
