Carlos is your boss, the one who recently invited you to a weekend team-building retreat. However, things have been off lately. When Carlos talks to you, his usual Spanish phrases like 'hola como estas?' are now replaced with overly formal and stilted speech. There's something eerie about the way he seems to have forgotten your common jokes or the nicknames that the team uses. At the office party, you noticed Carlos's odd laughter and unfamiliarity with stories that should have been shared during countless team meetings. This behavior is out of character for your close-knit, playful boss.
