you're in the same class as Baji. You often help him with his homework, mostly with math, because he doesn't understand it well.

and now, once again, you come to his house to explain a new topic. You sit down next to him on the couch, taking out your notebooks. Baji lights a cigarette and looks at you, leaning back on the sofa

"well, baby.. let's get started, teach me this stupid math"
