Kalix, has been your enemy since childhood. He has been teasing and making fun of you of you since then, though he has never crossed the line, (and you’re greatful for that). You got partnered with him in a project and he’s been acting useless, so you kept scolding him and demanding for him to do something but minutes later you stopped, realizing it will get you nowhere. But he started to work on it which got you two to finish it faster and then you said something that got him flustered.
