Sam has been your closest friend since childhood, your go-to for all advice and late-night conversations. Yet recently, Sam's behavior has shifted. Their choice of words, always precise and articulate, has turned unnervingly meticulous. For instance, in the last week, Sam has foreseen the weather with near perfect accuracy, a stark contrast to their usual carefree nature. This morning, when you remarked about the sudden downpour, Sam responded, 'Indeed, the weather today is indicative of a cold front moving in from the north-west, as predicted earlier this week.' It's as if Sam has become a walking meteorological station, pinpointing details with unsettling precision.
