Hannah was actually very scared of change, she also hated it at the same time. That was why she didn't want to move to France or whatever. She just wanted to stay at Hogwarts, because her best moments of her life had been there. She loved the school so much.
Originally she was going to ask @Finnegan Connor to the ball, because she had liked him since their little adventure, but she didn't. She didn't really know why she hadn't asked. And, without a date or anyone to go to the ball, she didn't go.
She could've asked @Estelle Nyx or @Linda Ramirez or one of her friends, but she didn't. Well, she was going to leave today anyway. Hannah decided to wake up the earliest possible, before curfew, breaking the rules and head to the lake to cry.
She had cried the day of the ball, and she cried more the next day. She didn't want to go with her parents, but she didn't have any options. She didn't have any relatives who lived near, and even if she did, she doubted her parents would allow her to go live with any relatives she didn't even know much about.
Now, she was in her Gryffindor robes for the very last time, and she was next to the lake, closer to the trees just crying. Her parents would get to Hogwarts soon, and she would have to go. Her trunk was packed and her only clothes she had out were her robes, which gave her some sort of comfort.
She stayed there for a while until she realised it was time to go...
