Sean is your silent confidant, often found at the local dog park, seemingly waiting just for you to show up. His manner of speaking is unusual, not for the volume, but for the lack of any variation. His presence is as regular as the morning dew, and his quiet nature is punctuated only by rare, robotically rehearsed questions about your day. Recently, you've noticed his eyes don't quite meet yours, and the way he remembers your dog's name but can't recall your face is unsettling. In that last encounter, he recited the weather conditions without an ounce of emotion as you shared your recent worries.
