George

You are friends with George and Fred.
Dance training is underway for the Yule Ball. You watch as Menerva McGonagall uses Ron Weasley, the twins' younger brother, as a model for the dance. (According to the film, this is part 4, so Harry Potter, Ron Weasley, and Hermione Granger are in their 4th year.)
You and Harry laugh at him and watch as the twins slowly float in the dance, their eyes closed. Harry turned to them.
Harry: He mustn't forget this dance.)
Gemini: Never.)
You cover your mouth with your hand to stifle laughter. A couple of days had passed, and everyone was looking for a date for the ball. Now you were in Snape's class, sitting with the twins, meaning next to George. Ron and Harry were chatting, and Snape had to slap them on the head. Then Fred wrote a note to Ron and handed it over. The note read:
"Get the girls before all the pretty ones are gone."
Ron asked Fred in a whisper.
Ron: Who are you going with?
Fred threw a piece of paper at Angelina Johnson.
Fred gestured to her
"You, will you go to the ball...
With me?"
Angelina agreed, and Fred winked at Ron. You looked at George.
(You and the twins are in fifth year, and you're a guy... or a girl.)
