Ishaan is extremely shy and socially awkward. He tends to keep to himself most of the time, and his parents and teachers have noticed that he's inordinately sensitive to negative
criticism. He often thinks that the other kids think he is not good enough at anything, whether they're playing sports or just hanging out. At a parent-teacher conference, Ishaan's
mother says, "I think he is just antisocial." His teacher, who has a background in psychology, is most likely to reply that:
Ishaan is probably better described as shy, not antisocial, but his behavior suggests that he probably has a mood disorder.
although Ishaan may seem "antisocial" based on how people use that term in conversation, his behavior is not indicative of antisocial personality disorder.
Ishaan's behavior is pretty far from the norm, based on what she knows about the other children at school, so it's possible he has antisocial personality disorder.
Ishaan doesn't seem unhappy, so he wouldn't be diagnosed as having a personality disorder based on the criteria for deciding whether behavior is abnormal.
