This is what certain mental illnesses do to a person’s mind, they impair healthy functioning.
Why do you think it takes 6, 8, 10 years of professional training for a therapist or psychiatrist to begin to have the competencies required to help someone who is severely mentally ill? Because their mind is not functioning like yours. Your version of Cho as petulantly bad is ridiculous. Some mentally ill people cannot distinguish between friendly and unfriendly behavior, they may be paranoid, delusional, they may be capable of connecting and functioning in some ways, but not in others. Stupid, ignorant people like yourself cannot even begin to understand what is going on inside the mind of someone mentally ill.
