For the past weeks, Sam, your usually attentive best friend, has seemed distant. Despite this, they're still overly attentive to your activities and ask about them with an eerie consistency. Last week, you noticed Sam's smile was unnaturally wide, almost like a perfectly painted mask, during one of their rare greetings. At times, Sam seems to echo your words too precisely or asks questions about your past that feel off, as if they're trying too hard to appear knowledgeable about your shared history.
