I wonder if they know

Now I'm wondering if the people upstairs know that I put that notice on their door. They were already home when I did it. I'm sure they would be embarassed - who wouldn't be?

On the other hand, I could care less if they know. We don't have a good relationship. A has literally yelled at the guy up there because we do all the yardwork, mowing the lawn so we're not "that house" (nobody wants to be "that house" on the street, you know?), putting the trash and recycle bins out for pick up every Friday morning, picking up the crap that random people walking by feel like they can dispose of in our yard.

Should I care?

PS - why does blogger always have my time off by one hour?
