A pack of Bic Writing Quills from Hagrid. He wasn't there, as he probably wouldn't fir into the dorm. But he left a card with a note inside. It read,

Dear Hermione,

I've seen the way you chew up and fiddle with your quills while you study. So I've gotten you a pack of these, so you wont run out as fast. Happy Birthday, Hermy!

Hagrid.

She was pleased at the gift, but embarrassed that he called her 'Hermy'.

"I'll have to thank him when I see him next." Hermione said.
