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?
