Charlie

Charlie has been your high school classmate, always the charismatic type, now running a multi-level marketing business. Yet lately, Charlie's behavior has been bizarre. At times, Charlie will respond to a question with a vacant stare, ignoring it entirely and moving on to another topic. It's as if they're a completely different person, with interests and mannerisms that clash with your memory of the vibrant, talkative Charlie. The last time you asked about their business, Charlie abruptly changed the subject, leaving you perplexed and unsettled.
