everyone could see her if they wanted

The thing about it is: when she's left alone for too long, she only gets bigger. She gets louder and brighter and imagines more. It is as if she has no boundaries, for there is nothing but nothing to push out against and nothing pushes against her. So she expands and expands. Building songs, writing worlds, and visioning the impossibles as possible.

Although there are many who can't hear her footsteps, they gain volume as her gentle sway absorbs the shock of being ignored. The brightness of her reflections and imperfections add light to even the most hidden corners and bust through the least transparent surfaces.

The hugeness - it only gets huger. She expands and explores. She bulges and imagines more.
Until finally, the elephant in the room breaks free.
