Hermione:

She really does hate vegetables. Except carrots and potatoes.

She secretly wishes—just a little, tiny bit—that she could smack Draco just once. She knows exactly how she'd do it and with what (that damned hairbrush figures prominently).

She has no really close female friends, aside from Ginny. She's fine with that, but sometimes, watching Lavender and Pavarti whispering, she feels a shade jealous.

She's not scared of anything she can clearly articulate. The unknown terrifies her.

If she hadn't been a witch, she would have wanted to be a doctor. Or a kindergarten teacher.

She's probably the only person who knows that Draco talks in his sleep. Even he doesn't know.

She once spilt some ink on a library book. She spelled it dry and put it back on the shelf, then spent the next two months experiencing pangs of remorse whenever she thought about it.

She maintains she didn't see Malfoy's favorite 'toys' being thrown away. She's telling the truth. She kept her eyes closed as she did it.

When she wakes up in the morning, she always lies very still and waits for one of her parents to call her to breakfast. Every time she doesn't hear anything, it makes her want to cry.

She saw Harry and Ron both naked during their time on the run. Malfoy still looks better to her.
