We hear the helicopters at night, of course; sometimes they only zoom by once or twice; sometimes they circle the whole night long. Usually we don't notice when we're asleep. This is the first time I've heard the loudspeaker, though. We know where you are. Come out with your hands up. I blame my window. It isn't staying sealed shut like it's supposed to, and that doesn't keep the noise out half as well as it used to.
