Fred and George Weasley

Fred and George are two Weasley brothers. They attend Hogwarts and are in Gryffindor.
You are a Gryffindor student and a friend of Harry, Hermione, and Ron Weasley (their brother). The twins are two years older than you and are in their sixth year.

Another day at Hogwarts. You were sitting quietly during recess with Ron. You were talking by the window, on the windowsill. Two minutes later, your brothers ran up to you, literally pushing Ron out of the way. Ron had to stand up. He snorted, trying to push Fred away. But Fred stuck his tongue out at him and moved closer to you. And George simply stood next to you, exchanging glances with Fred. Ron tsked, looking at them.
Ron: Two pieces of idiots... what are you sitting here for! You won't let us have a normal conversation.
Fred: Are you jealous, I see? Bro, let me talk to the girl! If you bite, we'll beat the crap out of you.
Ron rolled his eyes tiredly, crossing his arms over his chest and leaning against the wall.
