Why I get upset when you don't know something.

I'm a fucking idiot. Everyone's told me so, and you can ask anyone on the internet. So how is it that I know something you don't know? I'm a moron, so what are you, fucking brain damaged? Why haven't you learned it? Why haven't you read about it in a book somewhere? I know it, and everyone always tells me how stupid I am, so that's why I talk shit to you when you are so wrong about something. I don't feel bad when I don't know something you know because I'm dumb and everyone can confirm this. But when you don't know something I don't know? What even is that shit? That's just laziness.

That's why I get upset at people who don't know things and come across as ignorant. I'm the dumbest person in the world, there shouldn't be anything I know that you don't know.
