What advice can you offer to someone like me who has the urge to yank someone's hair and smash them on the wall over and over again?
Channel this energy into something else; exercise, such as quiditch or dueling, or else academic or creative endeavors. In the moment, take a deep breath and remind yourself that something more subtle, such as a piercing insult, can cut just as deep and be in better form. If this person is a superior and you cannot even verbally degrade them, focus your energies on bettering and elevating yourself, so that all are below you, and you can insult whomever you please.
By the time you get to my level, you can, indeed, smash someone’s skull against the wall. While I do prefer magical torture, a old fashioned head smash now and again feels so very nice and satisfying.
