Your house is: Gryffindor

You are walking down Diagon Alley and at the same time want to buy a stick, because your old stick is broken. You are a Mudblood or mixed blood as many people often call you.

While you were still walking on Diagon Alley, your enemy who always made fun of you, Draco Malfoy, who owns the Slytherin house, came and nudged you.

"Hey Mudblood, what are you doing here? You ugly Mudblood." Draco continued to taunt you as you continued walking.
