1. Friends
Draco announced that the only students staying at Hogwarts were the ones whose parents didn't want them, so Harry has detention today. He gets tired of the way Draco forgets that not everyone is like him. Harry's parents are dead. No-one else has trouble remembering that.
It's a sore point for Harry, people wanting him around, and that's really why he hit Draco in front of Weasley and Snape and everyone. He wouldn't have gotten half the detention if he'd punched Weasley instead. He scrubs cauldrons. It's small consolation that Snape doesnt have anything else to do on Christmas either.
2. Presents
Draco's is just the size for sweaters and holds one when Harry opens it under Snape's scrutiny. But sitting alone on his bed, he finds a pair of Firebolts, wedged in with a spell that makes his eyes hurt. Harry grins and stows them away under Draco's bed.
When he turns back, there's another box on the bed. Harry's is the only name on it. It's wrapped in purple, red, yellow, and blue, which clears Snape altogether. More clothes - a cloak that Harry disappears in. Really disappears, he realizes. The invisibility feels even stranger than the fabric, but Harry adjusts.
3. Family
The Dursleys sent fifty pence taped to a card that doesn't say Happy Holidays!, but it gets lost in the excitement of being invisible and trying to make Hagrid's flute sound more like Hedwig.
Next morning, he finds it in his pocket. He flips it into the air at breakfast, catches it again and again. It's something to do. "What's that, Potter," calls out a Weasley from across the room, where the four of them sit together. "A practice Snitch?"
He looks at the coin in his palm, worn and discolored and a little bent. "No. It's an insult."
