Our upstairs neighbor has a bullhorn. I've seen him use it to talk with stranded mortorists on the freeway, not 30 feet from his window.
Last night around 2:30 AM, we were finally headed to sleep after our return from College Station to see my cousin graduate. Only I hear a voice from above, whose I presume was my neighbor:
"Don't break into that vehicle. You are being surveilled."
It was great to hear the word "surveilled" in the middle of the night.
