Washing windows

Date: 4/9/2017

Several stories high, I was on someone's terrace, washing the outside of their apartment window. I also noticed their brown window blinds were filthy and started to clean those, too. At one point, I stood on the window, which opened horizontally, so I can get some extra height to reach the top of the window and the top of the blinds. It felt like the blinds required a lot more work and effort than what I was putting into it, and that it won't be seen or appreciated by anyone, so why bother?
