Answer:
I would give a piece of advice to Draco Malfoy. He is very self absorbed and arrogant. I would tell him to stop being like that, and be welcoming and friendly instead. Hurting other peoples feelings, for example when he insulted Ron, is not a good thing to do. He should make friends instead of bringing others down. I would also tell him to be supportive towards the other characters, and stop bringing people down.
