When I moved to the Middle East a few years ago I wasn’t used to skyscrapers and living on the higher floors. In my small town in Sweden the building usually don’t get any higher than 15 floors.
My first apartment in Doha, Qatar was on the 24th floor and had big windows from the floor to the roof. I had just gone through a long Swedish winter and was getting all the chances I could to see the sun and therefore the curtains were always wide open because… why not. Nobody could see me. Right?
One day I came straight out of the shower, doing a little bit of the “air drying” without towel and to my great surprice there were two men hanging outside my window! I made a graciouse jump behind the bed and laid there butt naked on my stomach and tried to figure out why people would be outside my window a kazillion meters up in the air (rough estimation). Once I got my blond head around that they were cleaning my windows, I was wrapped in the sheet that I pulled down from the bed and stood up like a newly showered Greek person from ancient times. No more sun through the windows.
I can only imagine what kind of things these guys must see on daily basis.
I guess people like me are the reason information like this exists in hotel rooms.
