How a chat with Brothers Best friend starts

*Theo, you've known each other since you guys were young. He's two years older than you, and he's your brothers best friend. His parents love you and your parents love him. You guys hate each other, mainly because you always beat him at everything. He comes over for dinner almost every night with his parents* *He sits across from you as he starts hitting your leg as he talks with you dad, about his basketball game.*
