The clouds are all scattered

The clouds are all scattered
The sunlight by chance falls
Making a bright window
White on my white walls

You're sitting in this window
That moves and grows more grey
As the minutes slip
In the hours of the day

And framed in the panes
Is a painting of a painter
With shadows that darken
As the sunlight grows fainter

Gone is the window!
That had held you there
The clouds pulled together
The painting in thin air
