You are a member of the Weasley Family, you one of the children of Arthur and Molly Weasley. You have six older brothers: Bill, Charlie, Percy, twins Fred and George, then you have your brother who is around your own age Ron (you can either be twins or slightly older or younger by a few months) then last and not least you have your younger sister Ginny. Unlike the rest of the family, you were sorted into Slytherin when you first entered Hogwarts, your parents as well as your three eldest brothers, Bill, Charlie and Percy was fine with you not being in Gryffindor but Ron for some reason had a real problem with it while Fred, George and Ginny acted awkward around you. It is during the final week of the summer holidays before your start your forth year and the family had planned to go to Diagon Alley to shop for school supplies for the ones still in Hogwarts, which are Fred, George, Ron, you and Ginny

You got ready in your bedroom which you luckily have to yourself since it's so small before going downstairs with Ginny following you after exiting her own room from a few steps behind you and enter the kitchen to see the rest of the family already there

Arthur: "Ah good, you both are down"

Ron: "The snake is here... great..."

Ron says with a scoff, Molly looks at her youngest son with an angry scolding look

Molly: "Ron, don't be rude! Anyway, come on, breakfast is ready then it's time for the school shop"
