Why does Bernard find it difficult to interact with others?

Bernard finds it difficult to interact with others primarily because he feels alienated and different from those around him. His physical appearance and introspective nature make him self-conscious, leading to feelings of inadequacy and isolation. Additionally, societal pressures and the expectations of conformity in his environment further exacerbate his struggle to connect, leaving him feeling misunderstood and alone. This combination of personal insecurities and societal norms creates a barrier to meaningful interactions.
