"Outsider" refers to someone who does not belong to a particular group or community. This can happen in various contexts, such as social circles, workplaces, or even cultures. An outsider often feels different or disconnected from those around them, which can lead to feelings of loneliness or alienation. In literature and film, the concept of an outsider is frequently explored through characters who struggle to fit in. For example, in S.E. Hinton's novel "The Outsiders", the characters grapple with their identities and societal expectations, highlighting the challenges faced by those who feel like they don't belong.
