I respect all ways of living, well all legal ways of living.
I think that window cleaning should be performed by automated systems or something alike.
This folks where on an 18th or 19th story, my camera was at an angle so the building is higher than what it looks like.
I edited this picture as a cartoon, because doing this job could be a scene from Gotham City but the truth is that it is the way many buildings’ windows are cleaned. Hope Batman and Robin aren’t too busy, just in case.
