For anyone interested in forming backstory with Ruth Ann, here's the basic run-down:
She excels at History of Magic (dead people! how COOL) and does well in Charms and Defence Against the Dark Arts. She'd probably like Herbology more if she had more patience and if she'd realise that it's just digging around in the dirt >.> Classes she does not do well in are Potions and Flying - her potions either fail or explode and her broom is rather reluctant to get off the ground.
History-wise, Ruth Ann was born in London to an American Muggleborn mother and an English half-blood father while her parents were visiting her father's sister. Until the age of five she lived in Venice, California, at which point the family moved to England for reasons having to do with her father's occupation as magical stone and jewelry assayer. Though she barely remembers her time in the States, Ruth Ann is of the firm belief that she and England are not meant to be - simply put, time and Ruth Ann's own desires have transformed California into a magical place of much better weather and a much more understanding environment. A large part of the reason behind this fanciful reworking is that she's frustrated with herself at the moment, being unable to preform as well as she feels she should be able to, hindered as she is by her ADD.
Ruth Ann is a bit kooky and a little off the wall. Think of her being like Luna Lovegood, only a little more focused and a little less gullible. She'll likely be friends with your character if they're willing to put up with her zaniness and don't care about her blood status. And if your character has a pet snake. She likes snakes. A lot.
