Hermione'd worn long sleeves to avoid accidentally touching anyone and, as the flat filled up with people and got steadily warmer, she began to feel overheated.  She'd greeted more people at the door than she could recall, almost all of them Malfoy's friends.  She'd had no idea he was so popular but she supposed money could do that for a person.   She nodded tightly at Blaise Zabini when he came in, had to snatch her hand back out of the way before Theodore Nott, who she only vaguely remembered from advanced potions could kiss it,  and just goggled at Greg Goyle.   She'd had no idea he and Malfoy were still friends, but he looked exactly the same save for the receding hairline.
