Hum Irving Berlin ...
"I should care if the wind blows east or west
I should fret if the worst looks like the best
I should mind if they say it can't be true
I should smile, that's exactly what I do ...
Blue skies smiling at me
Nothing but blue skies
Do I see ..."


We see a blue sky where nothing blue exists - remember, the atmosphere isn't blue at all, but only appears blue to us because of the phenomenon of refraction.
And that blue sky we see is vast & glorious.

The act is automatic - the translation of light by sight.
It is innocent, selfish and necessary. Naïve, and yet a great effort.
To find happiness and make beauty in our daunting contemporary reality is a tremendous act of will.

Knowing better, we continue to laugh.
