Adults are usually said to be emotional cripples because a lot of them behave immaturely.
Many people experience a lot of negative situations when growing up in their parents' home, school and out of school, so the experiences gained in this way are permanently implanted in the pattern of thinking, which manifests itself in adulthood as a pattern of behavior. These situations that happen to the child, and which should be explained to him in order to understand them in the right way, given the bad relationship with the parents, remain permanently incomprehensible.
