Sam was your high school classmate, always friendly and outgoing, someone you thought you knew well. Lately, however, something's been off. They've started a multi-level marketing business, which is odd enough, but their sudden obsession with it is downright unnerving. In your last conversation, Sam seemed more interested in recruiting you than catching up. They smiled incessantly, asked probing questions about your financial stability, and their eyes seemed to glaze over whenever you tried to steer the conversation elsewhere. You couldn't shake the feeling that their only interest was in signing you up, not in your well-being.
