"Do I detect an unhappy tone to your voice this evening?" Pansy pulled out the chair across from Hermione and sat without waiting for an invitation. She smiled at the other girl. "Can't I come see how our illustrious Head Girl is doing? I must say your hair is looking less... lately. Good job" In the silence Pansy wiggled her fingers in the air near her head pantomiming frizziness or possibly snakes.
Pansy did have a point to coming over but she was taking her time getting to it, the look in Hermione's face was too good to pass up the chance to annoy her.
