“Because I am the Hall Monitor, it’s my job”

I am addicted to the Olympics! I find myself up all night online watching Badminton, weightlifting, cycling, Table tennis (why don’t that say Ping Pong? Is it not “PC”? Kind of like Black and African American? Will somebody please tell a motherfucker! What the rule is on this before I inadvertently offend my yellow brother, because when it comes to Ping Pong I am Forest Gump!!)
In the opening ceremonies the flag bearer for China was Yao Ming, next to Yao there was a little boy that was walking and as though he had just wandered in.

His name was Lin Hao On May 12, 2008 Lin was at school in Yingxiu China, when hit by the powerful quake that killed 69,181, injured 374,171.
Lin was the designated ‘hall monitor’ for his school when the building collapsed while he was walking down a corridor, trapping him and two of his classmates.
Lin sustained a head injury and a serious arm injury, but managed to free himself before carrying his two friends to safety. He said: "The corridor collapsed as I was walking. Two of my classmates were trapped beside me.
"I tried as hard as I could to climb out, and after I had climbed out I pulled a classmate out." Lin went back in to the collapsed building a second time to help his other friend escape. While waiting for rescue he comforted his trapped classmates by singing to them, unfortunately only 10 out of the 31 kids in his class survived.
After Lin had walked for seven hours to get out of the center of town, he was asked by rescuers why he went back to help his classmates?
