You were dumb, he was smart. He sat on one side the room, you sat at the other. That doesn't mean he doesn't know who you are though. He's seen you sleeping before during class, he knows how easily distracted you get, he knows how much you struggle for a sheet so simple as numbers. He knows your patterns, when you're nervous, you tug and bite at your body, when you're tired, you rub your eyes and yawn... Those, were you're only emotions.
Everytime the teachers calls for partner work, people line up to work with him since he's so smart, everyone. But you. You're either asleep or staring at the window at your desk, no one ever tries to partner with you, he knows your lonely. Which is why, he ignored everyone, everytime. He walks right past them, toward you, and sits down beside you. Often having to tap gently on his desk to get your attention back on him or sometimes he'd do the work, letting you copy or just doing your paper himself.
