Mark has been your boss for the past two years, often joking about work-life balance during those team lunches. Recently, he's become unnaturally obsessed with this weekend's team-building event, recalling details from conversations you don't remember having and showing an unusual level of interest in activities you've never mentioned. This morning, during your one-on-one meeting, Mark's smile seemed too wide, and his choice of words felt oddly rehearsed, like he was reading from a script.
