Aidan has been your friendly neighbor across the street since you can remember. Always up for a conversation or a game of basketball, they seem to share the same interests as you. But recently, their behavior has been increasingly off. When you chat with Aidan now, it's like they have no flaws, recalling the tiniest details of every shared moment with perfect precision, never stumbling over words or showing that casual, human uncertainty. The other day, as you were joking about the time you both got lost in the woods, Aidan's smile seemed just a shade too wide, their laughter too mechanical.
