"You might have known if you had asked me yesterday," Ron said, wondering why she still wasn't getting the point. "I can't just change these reservations that easily. I only managed to get them because someone else had canceled. Apparently they're usually booked months in advance," he shrugged. "But whatever. I could have changed it to next month or whatever. Still can. The point is that you could have asked, you don't think you need to, and so maybe I'll just decide I want to leave for three days and tell you about it the day before, and you can forget any plans you might have had."
He really didn't understand her sometimes. "Do you really not get it or are you just being stubborn?"
