Aimée felt her shoulder ache as she finally reached the library. Her whole bag was filled with books she had taken with her from the library one at a time to use them in the common room of Gryffindor. She never felt the need to return them when she didn't need them anymore; the library was not a place she passed often. These books had been piling up beside her bed, not remembering she was allowed to lent these books for only a few days. An attention paying fellow Gryffindor reminded her of this, telling her that the librarion wouldn't be happy when Aimée would ever return these long-expired books.
So now she was carrying this way too heavy bag. The girl could've used a spell to lift the books from the ground and let them float to the library, but she didn't want to be seen like that - a short girl that was surrounded by a whole bunch of big, flying books walking through the hallway. Not to mention the fact that the halls around the library were usually crowded; the books might bump against heads and other vulnerable body parts of other students. Non, Aimée would rather not attract attention in such way.
As the Gryffindor entered the library, she looked around where she could deposit them. Ah, there! She approached the table, where she was supposed to hand her books over to someone who would take them in. That someone was not here.
Smiling to herself, she quickly put the books on the table. There wouldn't be any accusing questions thrown at her to why she had so many books! This must be her lucky day. Her shoulder immediatly felt better after releasing them from the weight of the books.
Just as she put down the last book, Aimée heard someone enter the library behind her. With a quick glance, she realised that it was the librarian. Retreat! She quickly jumped behind a bookshelve, and slid to a more quiet section of the library. I'm behaving way too suspicious! Then the girl spotted a table, away from the other tables, with a lone Ravenclaw girl sitting at it. Perfect.
Aimée sat down next to her, trying to look as normal as possible. The other girl didn't seem to notice her. Was she asleep? No - her eyes were open. Amazing, Aimée thought, to be so skilled in concentrating that one didn't even notice someone sitting next to them!
The Gryffindor was pretty impressed. But it wasn't very polite of her not to say anything. Aimée took a breath. "Uhm, hello there!"
