Relaxing on the couch in the sitting room, I can see out the big picture window in front of me. The view isn’t spectacular - the houses across the street - but I can see the sky, so strongly blue at this time of year, and I like it when the great cumulus clouds build in the afternoon, towering and white. Later they may gather and darken and the sun is hidden in the purplish blackness of a coming thunderstorm.
Sometimes I watch the trees sway in the wind. They are filled with leaves now of course, the brightness of their spring verdure fading into the waxy dullness of a hot summer. But against the white of the clouds in the blue sky, the scene is colourful and vibrant.
Then I notice that some of the window’s pane is not as clear as it should be. It presents a hazy, blurry effect of the outside. The lower left corner of the glass looks smudged and unattractive. I just cleaned the window a couple of days ago. How did that corner get like that?
