We hadn’t been in the new house long before I suspected something was very strange. It was the noises at first. Initially, they were soft echoes that repeated the words me and my wife would say. Only in the bedroom, though. And this was awkward, as well, because it would repeat us during noisy sex. Each moan and groan would play out on a three or five-second delay, inevitably distracting us and making us stop. The echoes repeated the noises our dog made, too.
