Shadows form through the obstruction of light by objects, and the duration of a shadow corresponds to the duration of the light source and the object. The absence of a shadow suggests either constant direct overhead light (impossible) or a light-generating or light-absorbing property within the object itself. The claim's second sentence reframes the phenomenon: 'nobody follows.' Shadows aren't optical phenomena but representations of social following. The absence of a shadow isn't physics. It's isolation so complete that social connection itself is absent. The person exists in a state of visibility without attachment.
