Scene: I asked a senior student to make some copies for me (he is an office assistant during some periods).
Student: "Ms. Daley, I ran out of paper."
Me: "That's ok. I need it for next period."
Student: " OK. I need to wait to get paper."
Me: "You could go to the offside closet."
Student: "I have to wait for a teacher. She's producing milk right now."
