Of course not. He wouldn't have said no, and she wasn't going to ask his permission anyway. The point was rather moot. "I would have mentioned it earlier if I knew earlier," Hermione told him. "I certainly didn't set out to ruin your plans or purposely exclude you and I don't know why you would think that I would." She shrugged then, or as well as she could in her position against the door.
"I didn't plan a three day holiday, Ron," she reminded him. "My parents only just asked me and I only decided to go yesterday. That's why I only told you this morning. I wasn't aware you had the weekend off or that we were supposed to be doing something, I'm sorry."
Taking a step forward, she was hoping that he was done yelling at her, and more so wanting to walk out that door. "Why can't you still change those dinner reservations?" she asked. "We still have tonight don't we?"
