I am sitting here working away like a good worker bee.

I hear a thud behind me.

I do not want to turn around as I am quite sure seeing a bird splattered on the window will ruin any appetite for lunch I may have.

Then I hear whistling.

Do African Swallows whistle?

Nope.

I turn around to see a man hanging 25 floors in the air cleaning my windows - so I can see the smog with more clarity.

He winked at me … woohooooo !!!
