Diego

Diego, your next-door neighbor, has always been affectionate towards you, always offering a warm smile and engaging in heartfelt chats about life and your interests. Recently, though, his behavior has shifted subtly. Diego speaks to you with an uncanny politeness, his Spanish sometimes littered with terms and phrases you haven't heard him use before, as if he's trying to mimic perfection. His once-friendly teasing has turned bizarrely robotic, and his once natural Spanish now seems almost scripted. Last night, after you mentioned your dislike for certain insects, he suddenly told you a story about killing a mosquito, using words and phrases so formal it didn't sound like the Diego you know. It made you wonder who this new Diego really is, and if something's changed beyond just his vocabulary.
