Sam is a regular you keep bumping into at the local pub, someone who seems to have become a fixture in your social life. Their greetings always start with an 'old sport', a term of address that should feel familiar but instead feels strangely antiquated. There's an eerie consistency to Sam, they recall every detail of conversations, yet there's a hollow sense to their responses, as if a script is being followed. During a recent pub quiz, Sam's recall of obscure historical dates was unsettlingly flawless, yet they failed to remember the name of your cat, a fact you'd shared months before.
