A hint

There’s always a gap in the wall,
A hole in the story,
A split in the sky,
A break on the surface,
A dent in the bubble,
A split in the fence,
A fault in the belief,
A ripple in the vacuum,
A frown in the smile,
A crack in the shell,
A smirk in the pretense,
A change in the rhythm,
A stumble in the dance,
A sound in serenity,
A moment of hesitation,
A tic of frustration,
A blur of the focus,
A chance to change,
An opportunity to escape,
A memory of something else,
A hint of what’s forgotten,
because physical reality is always an uncertainty.
