@BluePlanet okay. I'm not trying to be rude but she probably thought you overstepped a boundary by asking for specifics. Employers do not own their employees and it's really none of your business why she needs time off as long as she asks with plenty of notice. Most businesses require at least 3 weeks which is about what she gave you.

@BluePlanet 👆️ This.

In addition to what @SwampFlower said... not only was she [i]not[/i] being rude to you. She was in fact being courteous. Based on what you've said here, at least, she didn't tell you, "I can't work on the 12th of November." Instead, she checked if you thought you [i]would[/i] need her that day or not. That implies to me that if you had said, "Yes, I will need you" then she would've altered her plans so she could work.
