In which you see I am a slavedriver

Me (dumping a new pile onto the bed): "Come and fold, Delaney."

Delaney (coming in to fold): "I knew you were going to say that."

Me: "Wow. How do you know such things?"

Delaney: "Because, whenever you see a pile of laundry and then you see me, you say, 'Come and fold'."
