My Blue Sky - my blue day

No-one can see me so I am alone
As I look through the window to the day beyond
I see a  bright blue autumn sky; without clouds
it's a blank canvass in need of paint

A crow paints in the first colours
A black swoosh!
Movement from left to right
Then a cloud
White,
Slow,
Fluffy
and with a second,
Third,
fourth.

My blue canvass lasts all day
my blue mood lasts too
