When your coworker buys you a redheaded stuffed frog who sings and dances to She's a Maniac because she said it made her think of you, is that because you were singing that song and dancing in her office last week? Or is it that she actually thinks you're a maniac? Because if it's the latter, it seems like an elaborate, but admirably creative, way to tell me.
