I can see clearly now

When you ask to have your windows cleaned in our building, this is what you get: an Italian guy about my Dad's age, singing while he hangs out your ninth floor window. You can see, I think, how filthy the pane he removed is. The windows weren't spotless when we moved in, and we've been here four years. How bad was it? We didn't really need to use the mini-blinds for modesty anymore. We had to look for drops hitting roof-top puddles to tell if it was raining, because we rarely get rain on the window and couldn't see falling rain through the grime. It's a wonderful change.
