Korbin had stopped listening at that point. It's not like this boy had anything to say that would interest him, and like he had said, juggling a soccer ball took a lot of focus, more focus than could be split between juggling the ball and whatever nonsense this boy had to say.
"... a spoiled only child who gets everything he wants from his parents."
Korbin's head stared straight ahead, away from the soccer ball. A split second later, Korbin reared his foot back, kicking the ball on the way down square in to the boy's face, as hard as he possibly could. This would probably knock him down on to his back, or at least to a sitting position. As soon as the boy had fallen, Korbin pounced on him, leaning over his body, head tilted to the side. His face was still scarily blank. He didn't say anything, just stared at the boy dead in the eyes, with no readable expression. If the boy were to try to wiggle free or strike back at him, he would shove his shoulders in to the ground with surprising strength, using his knees to pin the boys arms to the ground rather painfully. After a good 15 seconds or so of staring, Korbin finally decided to speak. "I understand you're trying to protect your sister. But the damage is done, now isn't it? Nothing you can do about it now except get mad, but that would only make things worse, now won't it? Look at where you are. Pinned to the ground, helpless. Now, I'm going to get up, slowly, and if you move, we'll be sitting in this position a lot longer than you'd feel comfortable with." Korbin did what was promised, slowly releasing the pressure on the boy's arms before he was standing up again. After he was fully standing up, he reached out a hand to help the boy up. "If you have an idea of how to make this better, I'd be willing to help you out."
