It's a happy one.The principal at the school, Luyanda Nyoka, moves from the cameras to take calls. He is in high demand on Friday.Where it all started for Siya Kolisi. The story goes that after his mentor told him to switch schools, not only did he do that, but he went almost instantly.

He has ploughed back to his community."In doing so, according to Nyoka, he is investing in pupils' futures."We are 100% behind the Boks for the final. We are confident the trophy is going to come back to South Africa where it belongs."Around 17km from the primary school, is Grey High School. Pictures adorn some of the school's corridors where past pupils' achievements are honoured. Kolisi's face can be seen in many of them.He moved to Grey High School when he was offered a bursary, owing to his rugby exploits honed by his mentor at African Bombers, Eric Songwiqi.Boks making the finalRector Christian Erasmus has urged Kolisi to "live up to the moment" on Saturday. "But there is a joyous sense that everyone wants to be part of the moment."Go out and live off the energy that we've got your back," says Erasmus.#RWC2019 Kolisi, like many Old Grey High Boys who have excelled on the rugby field are well documented at one of the school’s corridors. We’re tracking all things building up to #RWCFinal tomorrow. @TeamNews24 pic.twitter.com/JbVNiF3Ru2— Kamva Somdyala (@kamva_somdyala) November 1, 2019Headboy at the school, Liyema Matyolweni, a rugby player himself for the first team has hailed the occasion on Saturday as motivational."It's a story of having a never-give-up attitude," Matyolweni begins, before offering his favourite moment of the world cup: the Boks making it to the final."
