When you encounter arrogance, you usually get angry. But when you come across someone who thinks they invented the world, your first response probably won’t be anger. It will be amusement. You have such a good sense of who you are right now that you’re not threatened by anyone else. The only exception to this reaction might be in the presence of an insecure authority figure who’s overcompensating. You can still find it amusing, but just don’t show it!
