Thanks, I Think?

When we got home from work tonight, we noticed that someone had raked the front yard. Didn’t clean the driveway or do the small side strip on the other side of the driveway, just the front part. It is not much because about half the yard is landscaped as a natural area, but it would take a person a half hour or so to do the job. There was a nice neat pile of the raked leaves in the street. Very strange. No other yard on either side of us was clean, nor across the street either. Did someone get that far before realizing they were at the wrong house on the wrong street? Is it like those wash your windshield shakedowns at intersections, is someone going to knock on our door tomorrow and want $20?
