“Nay, Sir, it was not the WINE that made your head ache, but the SENSE that I put into it''What, Sir! will sense make the head ache?''Yes, Sir, (with a smile,) when it is not used to it.”

“Yes, I answered you last night;No, this morning, sir, I say:Colors seen by candle-lightWill not look the same by day.”

“But I wasn't done," she pouted, no longer hungry for anything but him. "Yes, you were.""Yes, sir.""Lay down on your back.""Very yes, sir.”

“Do you remember me telling you we are practicing non-verbal spells, Potter?""Yes," said Harry stiffly."Yes, sir.""There's no need to call me "sir" Professor."The words had escaped him before he knew what he was saying.”
