At least when I dispose of the vermin, those enforcers in costumes will not be able to find a cause of death. Ah, the beauty of the Killing Curse.
And what exactly does this child wearing a sock hat mean by he "looks like Voldemort?" Is he saying something about how I look? I will never be able to make people understand their mistakes unless I punish them myself, but I don't have time for trivial tasks such as that. Especially when it comes to Muggles. There is no worse way to waste time than by wasting it on them.
