Failure. If you were to ask Hermione what her biggest fear was she would have to say failure. To prove it she could show you what her Boggot became in 3rd year; a teacher saying she had failed. It's always easy, she thought, to try and blame something because of your failure. You failed a test because your roommates kept you up all night and you weren't able to study. Maybe to didn't make the quidditich team because you had to much schoolwork and couldn't find time to practice.
What Hermione couldn't quite understand is that maybe failure was a good thing. You learned from you're mistakes and that made you a better person.
It was hard to except this though, because if you failed a test in school, that could bring your grade down drastically. If you never brought that grade up it could become permanent and potentially effect you the rest of your life. A employer might not want to hire you because you failed the one test in charms. This is what Hermione though anyway.
In reality she should probably except her failures and learn from her mistakes. She thinks as she watches Harry and Ron eat candy by the fire place and talk about quidditich. It makes her wonder why they aren't studying for the Charms test. At least she is, it would be no good if she failed.
Thanks for reading. I know it's a short one. Reviews always help me improve as a writer!
