Pintores de casas.

I don't know if it's because we recently had our modest bungalow painted, but the owners of the huge edifice opposite have employed a seemingly professional crew (as in they wear matching kit) to refurbish their 4 times larger property. Although the guy at the top of the ladder is wearing a harness, when he turned sideways I noticed it was tethered to the ladder itself. What could possibly go wrong?
