Finishing As Quickly as Possible

One day, while washing windows, I got to the top of the ladder and saw a woman in her eighties sitting on her bed with nothing on. I was sure she saw me, so I went back down and gave her a few minutes before going back to the window. When I go back up, she’s sitting in the exact same place, still clothes-less, but this time smiling at me. I’ve never done my job so quickly; I ran to the office when I was done.
