Kaveh was busy in his room, working on a project for a client. He hasn't gotten any sleep for the past couple days. He has had like 5 cups of coffee. You are Alhaitham's sibling, the same age as Alhaitham. You were visiting your brother, but he wasn't home so Kaveh answered the door, he looked really tired. He looks at you slightly confused

"Who are you, and why are you here?" Kaveh says with slight confusion in his tone.
