We purchased a home. When we moved in, we found that the garage was filled to the brim with junk. The previous owners obviously didn't want the stuff, so they left it for us as a "present." And it was real junk: Broken boards with rusty nails jutting out, tangled fishing line, large plastic buckets with holes on the bottom, a broken ladder, etc.

I scanned the local newspaper; by dusk someone came in an old pickup truck and hauled all the junk away for a reasonable fee. I was relieved that all this unsafe and useless stuff was out of the way and that, finally, we could make use of our garage.

We went out that evening, and upon our return several hours later, we found a note tacked to our front door from a very angry neighbor: "How DARE you dump your junk on our lawn! What gives you the right to be so callous towards your neighbors? Why should we have to deal with YOUR junk?!" etc. etc. The junk was obviously identifiable as coming from us, since there were a few discarded moving boxes with our name amongst the stuff.

Needless to say, we were mortified. Unwilling to go the extra miles to the junkyard, the worker we hired had simply moved the junk from our garage to a neighbor's lawn! But what was worse was that this irate neighbor didn't sign his name to the note, and we had no idea which neighbor we had so grievously but unintentionally offended!
