With social phobia, a person's fears and concerns are focused on their social performance — whether it's a major class presentation or small talk at the lockers.
People with social phobia tend to feel self-conscious and uncomfortable about being noticed or judged by others. They're more sensitive to fears that they'll be embarrassed, look foolish, make a mistake, or be criticized or laughed at. No one wants to experience these things. But most people don't really spend much time worrying about it. Here people are more concerns about others observation of themselves.
