"I just TOLD you what my plans were!" she reminded him. "Forget the owl then, how about I seek your permission in writing a couple of weeks in advance before I even think about leaving for a few days?" The look on Hermione's face was one that suggested she would never be doing any such thing, never mind the sarcasm. "I'm sorry if my parents want to spend a little time with me after everything." She wasn't, and didn't sound sorry at all and she glared right back at Ron.
"Don't yell at him!" she snapped when he yelled at Pig, annoyed that he was taking his anger out on the poor owl. "He didn't do anything."
