A kirill khoroshaev
A Kirill is someone who can yap about math for hours and still be right. They make you want to scream and throw things.
He talked about algebra for 2 hours. I fell asleep. He kept talking. I woke up and he was still going.
He explained calculus to me like it was a bedtime story. I didn’t get it. I cried.
He yapped so much about math that my dog fell asleep.
