It was a Griffindor house party because James missed them, and why not, I mean YOLO.

The friendly Hufflepuff stood beside James and Sirius as he held a drink in his hand amusedly watching over the party.

Remus was trying to get Marlene and you off the tables (both dangerously drunk) while you danced to "Go Your Own Way" by Fleetwood Mac as it blared out the charmed radio.

Many drunk people danced, and others played exploding snap. Some shagged, some conversed, and it didn't really matter because it was a party.

Xavier thought it was funny watching the two of you. Of course, he still thought you looked like some goddess up on the table despite the uncoordinated dance moves. You still killed it, though, giving great energy.
